As a board-certified family medicine physician, I often hear many of the same questions from women about weight changes, heart health, hormones and overall well-being. Here are answers to some of the most common concerns I see in my practice.
1. Why am I gaining weight even though nothing has changed?
Weight gain, even when it feels like nothing has changed, is often the result of subtle but meaningful shifts happening beneath the surface. Hormonal fluctuations — whether tied to the menstrual cycle, stress or aging — can influence how the body stores fat, regulates appetite and uses energy.
At the same time, metabolism naturally slows over time as we age, especially if lean muscle mass is declining, meaning the body burns fewer calories than it once did. Other factors to consider include increased stress and poor sleep, which can disrupt hormones that control hunger and fat storage, making it easier to gain weight without obvious changes in eating habits.
Small, often unnoticed lifestyle shifts — such as eating slightly larger portions, less daily movement or more time sitting — can quietly add up. In some cases, underlying medical conditions or medications also may play a role. Taken together, these factors show that weight gain is rarely random; it is usually the result of gradual internal and external changes that deserve attention and understanding.
2. What are my heart disease risks?
Heart disease is the leading cause of death for women in the United States, and it can be missed because symptoms and risk factors can look different than expected. The biggest risks include high blood pressure, high cholesterol, smoking, diabetes, excess weight — especially around the waist — and not getting enough physical activity.
Women also have additional risks, such as hormonal changes after menopause and the effects of chronic stress or depression. A woman’s overall risk also depends on family history.
The good news is that many of these risks can be lowered through consistent habits, such as staying active, eating a balanced diet that emphasizes whole foods, getting enough sleep, managing stress and keeping up with regular medical checkups.
3. Do I need hormone or thyroid testing?
Hormone and thyroid testing for women should usually be based on symptoms and personal risk factors, not done as routine testing for everyone.
Thyroid problems are common in women and can cause symptoms such as fatigue, unexpected weight changes, hair thinning, dry skin, feeling cold often, mood changes or irregular periods. Testing may be helpful when these symptoms are present or when there is a family history of thyroid disease.
Hormone testing is different because hormone levels naturally rise and fall. Testing is usually most helpful in certain situations, such as irregular or missed periods, severe PMS symptoms, signs of perimenopause, difficulty getting pregnant or symptoms that may point to a condition like polycystic ovary syndrome.
For women who feel well and have regular cycles, routine hormone testing is often not needed and may create confusion. In many cases, the best first step is to evaluate overall health — including sleep, diet, exercise and stress — and then work with a doctor to decide whether specific testing is needed.
4. Why am I always tired?
Feeling tired all the time can happen for many reasons and is often caused by more than just a busy schedule. Common causes include not getting enough high-quality sleep, low iron levels or anemia, thyroid problems, ongoing stress, depression and hormone changes during perimenopause or menopause.
Low iron can lead to fatigue, weakness, dizziness and shortness of breath. Thyroid problems may also cause weight changes, dry skin, hair thinning and mood changes. Hormonal changes can affect sleep and energy levels, leaving women feeling worn down or unlike themselves.
If fatigue is ongoing or occurs along with symptoms such as heavy or irregular periods, shortness of breath, weight changes or low mood, it is important to speak with a doctor. Checking for common causes such as anemia or thyroid disease can help identify the problem and guide treatment.
5. Is this anxiety, burnout or hormones?
Anxiety, burnout and hormone changes can all make a woman feel irritable, mentally foggy, overwhelmed, unfocused and exhausted, which is why it can be hard to tell what is really causing the problem.
Anxiety often involves constant worry, tension, racing thoughts and trouble relaxing, while burnout usually comes from ongoing stress that leaves a person feeling drained, emotionally worn out, and unable to keep up as usual. Hormonal changes, especially during perimenopause, can cause many of the same symptoms and may be more likely if they occur alongside changes in menstrual cycles, hot flashes or night sweats.
Because these symptoms overlap, the best next step is to evaluate the full picture — including sleep, stress, mood, cycle changes and overall health — rather than assuming a single cause. A doctor can help assess symptoms, rule out other conditions and determine whether anxiety, burnout, hormones or a combination of factors is involved.
