Physiological Changes in Pregnancy
Physiological changes occur in pregnancy to nurture the developing fetus and prepare the mother for labor and delivery. Some of these changes influence normal biochemical values while others may mimic symptoms of medical disease. It is important to differentiate between normal physiological changes and disease pathology.
What are Physiological changes?
Pregnancy causes physiologic changes in all maternal organ systems; most return to normal after delivery. These changes happen in response to many factors; hormonal changes, increase in the total blood volume, weight gain, and increase in fetus size as the pregnancy progresses. All these factors have a physiological impact on the pregnant woman: the musculoskeletal, endocrine, reproductive, cardiovascular, respiratory, nervous, urinary, gastrointestinal, and immune systems are affected, along with changes to the skin and breasts. The full gestation period is 39-40 weeks, and pre-term birth is classed as delivery before 37 weeks gestation, although there is variation internationally and it is thought that the length of human pregnancies also varies naturally.
The primary function of pregnancy is to allow for the growth and development of the fetus. All changes that occur within the mother’s body are intended to allow for this growth, as well as for the development of the placenta to nourish the fetus and sustain the pregnancy.
A pregnant woman will also become hypercoagulable, leading to an increased risk of developing blood clots and embolisms, such as deep vein thrombosis and pulmonary embolism. Women are 4-5 times more likely to develop a clot during pregnancy and in the postpartum period than when they are not pregnant. Hypercoagulability in pregnancy likely evolved to protect women from hemorrhage at the time of miscarriage or childbirth. In third-world countries, the leading cause of maternal death is still hemorrhage. In the United States 2011-2013, hemorrhage made up 11.4% and pulmonary embolisms made up 9.2% of all pregnancy-related deaths.
The increased risk of clots can be attributed to several things. Plasma levels of pro-coagulation factors increased markedly in pregnancy, including von Willebrand Factor, fibrinogen, factor VII, factor VIII, and factor X. Both the production of prostacyclin (an inhibitor of platelet aggregation) and thromboxane (an inducer of platelet aggregation and a vasoconstrictor) are increased, but overall there is an increase in platelet reactivity which can lead to a predisposition to clots. There is also increased blood stasis due to the compression of the vena cava by the enlargening uterus. Many factors have been shown to increase the risk of clots in pregnancy, including baseline thrombophilia, cesarean section, preeclampsia, etc. Clots usually develop in the left leg or the left iliac/ femoral venous system. Recently, there have been several case reports of May-Thurner Syndrome in pregnancy, where the right common iliac artery compresses the below left common iliac vein.
In general, the changes are more dramatic in multifetal than in single pregnancies. These physiologic changes allow the parturient to support the growing uterus and fetus and to withstand labor and the postpartum course. Because the gravida may require surgery while pregnant, it is important to have an appreciation of these physiologic changes.

Pregnancy
What is Pregnancy?
Pregnancy is the term used to describe the period in which a fetus develops inside a woman’s womb or uterus. Pregnancy occurs when a sperm fertilizes an egg after it’s released from the ovary during ovulation. It is the term used to describe the period in which a fetus develops inside a woman’s womb or uterus.
Symptoms of Pregnancy
You may notice some signs and symptoms before you even take a pregnancy test. Others will appear weeks later, as your hormone levels change. Many people notice symptoms early in their pregnancy, but others may not have any symptoms at all. Some early pregnancy symptoms can sometimes feel like other common conditions (like PMS). So the only way to know for sure if you’re pregnant is to take a pregnancy test. You can either take a home pregnancy test (the kind you buy at the drug or grocery store), or get a pregnancy test at your doctor’s office or local Planned Parenthood Health Center.
Pregnancy week by week
Pregnancy weeks are grouped into three trimesters, each one with medical milestones for both you and the baby. A baby grows rapidly during the first trimester (weeks 1 to 12). The fetus begins developing its brain, spinal cord, and organs. The baby’s heart will also begin to beat. During the second trimester of pregnancy (weeks 13 to 27), your healthcare provider will likely perform an anatomy scan ultrasound. During the third trimester (weeks 28 to 40), your weight gain will accelerate, and you may feel more tired. Every pregnancy is different, but developments will most likely occur within this general time frame. Find out more about the changes you and your baby will undergo throughout the trimesters and sign up for our I’m Expecting newsletter to receive week-by-week pregnancy guidance.
Infectious Diseases in Pregnancy
During pregnancy, some common infections that may occur are the flu, vaginal yeast infections, uterine infections, group B streptococcus, bacterial vaginosis, and listeria. Changes in immune function may cause this increased risk of infection, and if left untreated, may lead to serious complications. Urinary tract infections (UTIs) are one of the most common complications women experience during pregnancy. Bacteria can get inside a woman’s urethra, or urinary tract, and can move up into the bladder. The fetus puts added pressure on the bladder, which can cause the bacteria to be trapped, causing an infection. Infection can be dangerous during pregnancy as it can cause problems for unborn babies, such as hearing loss, visual impairment or blindness, learning difficulties, and epilepsy.
The first trimester of pregnancy is an exciting time and often comes with lots of questions about how you should care for yourself and your growing baby. Generally speaking, focus on taking good care of your changing body. Eat healthy foods, stay active, drink plenty of water, and get as much rest as you need. If you stay away from alcohol, smoking, drugs, and risky activities, you’ll set yourself up for a healthy pregnancy and a thriving baby. Don’t hesitate to ask your doctor any questions you have about what you should or shouldn’t do while you’re pregnant.

Understanding Blood Oxygen Levels
What is Blood Oxygen Level?
Blood oxygen level is the amount of oxygen circulating in the blood. Red blood cells carry most of the oxygen, collecting it from the lungs and delivering it to all parts of the body. A person’s blood oxygen level is an indicator of how well the body distributes oxygen from the lungs to the cells, and it can be important for people’s health.
Ways in measuring your blood oxygen level
There are two ways in measuring your blood oxygen level, arterial blood gas and a pulse oximeter. An arterial blood gas test is a blood test. It measures your blood’s oxygen level. The test also checks the balance of acids and bases, known as the pH balance, in your blood. An ABG is very accurate, but it’s invasive while the pulse oximeter is a noninvasive device that estimates the amount of oxygen in your blood. It does so by sending infrared light into capillaries in your finger, toe, or earlobe. Then it measures how much light is reflected off the gases. A reading indicates what percentage of your blood is saturated, known as the SpO2 level. This test has a 2 percent error window. That means the reading may be as much as 2 percent higher or lower than your actual blood oxygen level. This test may be slightly less accurate, but it’s very easy for doctors to perform. So doctors rely on it for fast readings.
How blood becomes oxygenated
Understanding how blood is saturated with oxygen begins with the alveoli or air sacs. There are millions of these microscopic air sacs in the lungs. They serve an important function to exchange oxygen and carbon dioxide molecules to and from the bloodstream. When oxygen molecules pass through the alveoli, they bind to hemoglobin which is a substance in the blood. As the hemoglobin circulates, oxygen essentially hitches a ride and gets dropped off to the body’s tissues. With this, hemoglobin picks up carbon dioxide from the tissues and transports it back to the alveoli so the cycle can begin all over again. The level of oxygen in your blood depends on several key factors, how much oxygen you breathe in, how well the alveoli swap carbon dioxide for oxygen, how much hemoglobin is concentrated in red blood cells, and how well hemoglobin attracts oxygen. Most of the time, hemoglobin contains enough oxygen to meet the body’s needs. But some diseases reduce their ability to bind to oxygen.
Measuring your blood oxygen levels
Generally speaking, an oxygen saturation level below 95% is considered abnormal and anything below 90% is an emergency. When this happens, oxygen therapy is needed, sometimes urgently. The brain is the most susceptible organ to hypoxia, and brain cells can begin to die within five minutes of oxygen deprivation. Should hypoxia last longer, coma, seizures, and brain death can occur. It is very important to determine the cause of low oxygen saturation in order to correct the problem. With chronic conditions, such as COPD and asthma, the root cause is usually low air exchange in the lungs and alveoli. In addition to oxygen therapy, steroids or bronchodilators may be needed to open the airways.
Treatment
The treatment options for low blood oxygen levels include supplemental oxygen. Doctors can administer oxygen therapy in an office, or they can prescribe or recommend the use of home oxygen therapy. A range of devices is available for delivering and monitoring home oxygen therapy, but some require a prescription. People can make lifestyle adjustments to reduce the symptoms of low oxygen levels, as well as improve their general health and quality of life. Eating a healthy and balanced diet can also help improve blood oxygen saturation. Since iron deficiency is one of the major causes of low oxygen saturation, eating foods that are rich in iron, such as meat, fish, kidney beans, lentils, and cashew nuts, can be helpful.

A Guide to Healthy Living for Seniors
What is Healthy Living for Seniors
As you grow older, you go through many changes, and you may need to adjust your lifestyle for healthy aging. Our minds and bodies undergo a wide variety of mental, emotional, and physical changes. While some aspects of life may become more difficult, active living for older adults is still well within reach. In this guide to healthy living for seniors, we’ll explore the many ways you can live a full, satisfying life well into your golden years. Healthy eating and regular physical activity can be keys to good health at any age. Making suitable lifestyle choices may also prevent some health problems, such as diabetes, heart disease, and some cancers.
What foods should seniors avoid?
Food plays a central role in all of our lives. Eating is both a way to sustain ourselves and an important part of our culture. People often mark major life events with a large feast from wedding cakes to birthday cakes, beautiful holiday spreads with family to casual lunches with friends. As adults age, they need fewer total calories, but higher amounts of some nutrients, especially calcium and vitamin D. In terms of nutrition, you need to focus on quality, not quantity. For both optimal physical and mental health, older adults truly need to make every calorie count.
Here are foods that you should cut down on (or avoid eating altogether) as you get older, and why:
- Raw or undercooked eggs, meat, and poultry.
Undercooked foods such as eggs, meat, poultry, and sushi can cause food poisoning, which can trigger sepsis and septic shock. Although anyone can develop infection and sepsis, seniors are at higher risk.
- High-sodium foods.
Too much salt can be a problem for older adults, especially if you have a history of hypertension. If your food is lacking flavor, try adding different types of herbs and spices rather than loading up with table salt. Additionally, always review the sodium content on nutritional labels.
- Caffeine.
Caffeine not only keeps many people from getting a good night’s sleep, but it may also increase anxiety and make your heart beat more quickly or irregularly. This could be dangerous if you have a heart condition. Caffeine can also be found in many teas, some sodas, chocolate, and even some medications, including over-the-counter pain killers.
- Sodas and sugary drinks.
Excess sugar also leads to obesity and other health issues. An ice-cold cola may seem tempting if you’re hot and thirsty, but sodas and many sports drinks contain a large amount of sugar. A cola can contain 39 grams of sugar in one 12-ounce serving, the equivalent of almost 10 teaspoons of sugar! If you have prediabetes, regular consumption of these types of drinks may raise your blood sugar to a diagnosis of diabetes.
- Alcoholic beverages.
Enjoying an occasional alcoholic beverage is harmless for many people. However, if you live with a chronic illness, such as diabetes, or you take certain types of medications, such as antihistamines, painkillers (analgesics), and medications for hypertension (high blood pressure), alcohol should be avoided.
Why is keeping a healthy weight important?
Aim for a stable weight as you get older. People of all ages need protein for strong, healthy bodies. Some older adults do not get the protein they need to maintain muscle mass, fight infection and recover from an accident or surgery. Keeping a healthy weight may help improve your health. The weight that is healthiest for you may be higher than that of a younger person. Ask your health care professional what a healthy weight for you may be.
Sometimes older adults feel lonely, sad, low, or stressed because of life changes, loss of loved ones, health problems, caring for other family members, or financial issues. Being good to yourself may help you improve your lifestyle habits, your “get up and go,” and your ability to cope with the demands of daily living.
Here are some ideas for being good to yourself
- Stay in touch with family, friends, or former coworkers to stay engaged and to keep your spirits up.
- See your health care professional regularly and share any concerns.
- Get enough sleep.
- Join a walking group or another social group.
- If you are retired, pursue a new hobby or volunteer to help keep you active and social.
- Surround yourself with people you enjoy.
Remember, it’s never too late to improve your eating habits, become more physically active, and be good to yourself for a healthier life. Strengthening your immune system and staying active can keep you healthier and make you less susceptible to illnesses throughout the year. You are never too old to enjoy the benefits of improved nutrition and fitness. With nutrient-rich foods and activities with friends, you can feel an immediate difference in your energy levels and enjoyment of life. In fact, as we get older, our food and activity choices become even more important to our health.

Blood Oxygen Level: What It Is & How To Increase It
What is Blood Oxygen Level?
The Blood oxygen level is the amount of oxygen circulating in the blood. Red blood cells carry most of the oxygen, collecting it from the lungs and delivering it to all parts of the body. There can be serious consequences if the oxygen level is too little or too much. Low blood oxygen levels can be a warning sign that immediate medical care is required. Maintaining the right oxygen level in the blood is crucial to maintaining good health. Similar to our blood pressure or blood sugar level, our blood oxygen level plays a significant role in maintaining good health.
What should your oxygen level be?
The oxygen saturation level is considered normal if it is between 95% to 100%. If the oxygen levels fall below this range, the person must seek medical advice. Oxygen levels between 91% and 95% may indicate an underlying medical issue. People with oxygen levels below 95% must take medical advice immediately.
Oxygen level below 90% is very concerning, indicating a medical emergency. The state is termed hypoxemia. Immediate medical help must be given to the person. If the oxygen saturation drops below 85%, the severe lack of oxygen affects the brain. The person may experience vision changes and lose consciousness.
When the blood oxygen levels drop below 80%, the brain, liver, and other vital body organs get affected.
Cyanosis develops when the blood oxygen saturation falls below 67%. It is a condition characterized by a bluish tinge on the skin or mucous membranes due to a lack of oxygen.
What are the symptoms of low oxygen levels?
Hypoxemia refers to a condition when the oxygen concentration in the blood gets abnormally low. Depending on how low the blood oxygen level is, the symptoms of hypoxemia may vary from person to person. Some of the symptoms of low oxygen levels in the blood include shortness of breath, headaches, restlessness, dizziness, rapid breathing, chest pain, confusion, high blood pressure, lack of coordination, visual disorders, sense of euphoria, and rapid heartbeat. When the oxygen level gets very low, it leads to cyanosis. The person experiences bluish discoloration of the skin around lips, fingernails, etc., due to inadequate oxygenation in the blood.
Ways to prevent low oxygen levels
With appropriate medical advice combined with changes in lifestyle and food habits, we can maintain appropriate blood oxygen levels and prevent them from getting low. Healthcare workers recommend the following to increase the oxygen saturation in the blood.
- Eat a healthy and nutritious diet
- Consider doing yoga and breathing exercises
- Exercising regularly
- Preventive medications such as inhalers
- Avoid triggers that may cause breathing difficulty, Be aware of your body
- Keep yourself hydrated
- Stop smoking
- Avoiding secondhand smoke
Many conditions can cause low blood oxygen levels. Treating the underlying condition responsible will generally improve blood oxygen levels. People living with chronic lung diseases, such as COPD, and those who catch COVID-19 may need regular blood oxygen monitoring. A person with low blood oxygen can also make lifestyle changes, such as adjusting their dietary and exercise habits. In conjunction with oxygen therapy, these changes could help a person raise their oxygen saturation levels. Early diagnosis and appropriate treatment are the keys to avoiding complications and ensuring good health. Book an Appointment with specialists in the field to get the right medical advice.

Insomnia During Pregnancy
It’s normal to have trouble sleeping at any point during pregnancy, but many expectant women experience insomnia starting in the second to third trimesters, as other pregnancy symptoms increase, and a burgeoning baby belly makes it harder than ever to get comfortable in bed.
Still, first trimester woes can force you from your cozy bed and disturb precious sleep too, including morning sickness, which can happen any time of the day or night, and a constant need to pee. But if you’re worried that a case of insomnia may harm your baby, rest assured it won’t. So do your best not to fret and sometimes, just letting go of these feelings is all it takes to help you sleep.
What is Insomnia?
Insomnia is a sleep disorder that makes it hard to drift off to sleep or stay asleep at night. This common sleep problem can also cause you to wake up too early and not be able to head back to dreamland, and it may make you feel as if the sleep you did manage to get wasn’t refreshing or restorative.
What Causes Insomnia During Pregnancy?
Insomnia during early pregnancy is usually due to factors such as hormonal changes. Many people experience insomnia at some point, during pregnancy. Better sleep hygiene, relaxation techniques, and cognitive behavioral therapy can help. Levels of the hormone progesterone are high during the first trimester, and this can cause sleepiness and napping during the day.
Aside from hormonal changes, factors that may make insomnia worse includes hunger, spicy foods, which may cause digestion issues, especially if eaten near bedtime, nausea, anxiety or depression, physical discomfort, and frequent bathroom trips. Other less obvious causes include difficulty breathing, with this difficulty sometimes affecting a person’s breathing at night when they are pregnant. This can cause snoring and brief pauses in breathing called apnea. Breathing problems during sleep at the end of the second and during the third trimester are more common.
Will Insomnia During Pregnancy Harm The Baby?
It’s understandable to assume that if you aren’t sleeping well, your baby isn’t either. But relax, your baby sleeps even when you’re wide awake. Your baby’s health is at risk, however, if your insomnia during pregnancy affects your ability to function. If you fall asleep while driving, or exhaustion leads you to stumble or fall, your baby could pay the price. Furthermore, research has found that women who have chronically disturbed sleep during pregnancy are at greater risk of gestational diabetes, preterm birth, depression, longer labor, and cesarean section. So it’s well worth doing what you can to sleep well.
What Can You Do To Improve Sleep During Pregnancy?
- Consider using a pregnancy pillow
- Diet and exercise
- Eat a healthy dinner
- Get a massage
- Establish good sleep habits.
- Create the ideal sleeping space
- Try to relax
Feeling exhausted is a common pregnancy symptom, particularly at the beginning and end of your pregnancy. However, if you always feel like you are finding yourself needing to sleep at all hours of the day, it may be time to speak with your doctor. They can make sure that no underlying medical conditions are causing this.
