It’s easy to dismiss fatigue, thinning hair and perhaps a little weight gain as normal. Don’t all women deal with these issues occasionally when busy schedules get the best of us? Not so fast. It may be more than just stress. Hypothyroidism could be the culprit. 

Hypothyroidism — also known as underactive thyroid — is a disease of the thyroid, a small butterfly-shaped gland located at the base of your neck just below your Adam’s apple. It’s the most common type of thyroid disease.  

When the thyroid gland works properly, it makes an ample supply of the thyroid hormone thyroxine. Thyroxine travels in your blood to all parts of your body and impacts your metabolism and hormone balance. When your thyroid gland makes too little thyroxine, it throws off your body’s metabolism.  

This means your body is going to be running slower, explains Anessa Alappatt, MD, Fairborn Medical Center. Since hypothyroidism slows down your body’s metabolism, it can affect a number of body functions, such as how fast you burn calories and how fast your heart beats. Dr. Alappatt talks about the symptoms of hypothyroidism. Click play to watch the video or read the transcript.

What is hypothyroidism and hyperthyroidism and what are their symptoms?

Hypothyroidism and hyperthyroidism are disorders of thyroid that affect the way your body runs. So, hypothyroidism means your thyroid is slow which means your body is going to be running slower. Symptoms of that are going to be you’re going to be tired, you can develop constipation because again things are slow. You can get swollen and then there’s common things that occur like headache, not feeling well, not sure what’s wrong with you and that you can actually see with hyperthyroidism as well, headache, not feeling well that sort of thing but your body’s going to be running faster so your heart may cause palpitations or you may feel a little shaky, nervous, anxious, diarrhea again your body is functioning faster. So some of the symptoms are the opposite but that general ‘not feeling well’ can be similar.


Common causes of hypothyroidism are autoimmune disease, surgical removal of the thyroid gland and radiation treatment. Autoimmune disease is the most common cause and occurs when the immune system mistakenly attacks thyroid gland cells. 

Women are more likely than men to have thyroid diseases, especially right after pregnancy or menopause. One in eight women will develop thyroid problems during her lifetime. 

What are Signs and Symptoms of Hypothyroidism?

Symptoms can develop slowly, often over several years. At first, you may feel tired and sluggish. Later, you may develop other signs and symptoms of a slower metabolism, including: 

  • Feeling cold when others don’t 
  • Constipation 
  • Muscle weakness or cramps 
  • Weight gain without eating more than usual 
  • Joint or muscle pain 
  • Feeling sad or depressed 
  • Feeling very tired 
  • Pale, dry skin 
  • Dry, thinning hair 
  • Slow heart rate 
  • Less sweating than usual 
  • A puffy face 
  • A hoarse voice 
  • More than usual menstrual bleeding 
  • Slow pulse 
Since hypothyroidism slows down your body’s metabolism, it can affect a number of body functions, such as how fast you burn calories and how fast your heart beats.

Identifying whether you have thyroid disease can be difficult. The symptoms are the same as many other health problems. If you’re struggling with an overall sense of “just not feeling right,” talk to your doctor. She’ll review your medical and family history plus order a blood test for diagnosis.

How is Hypothyroidism Treated?

Hypothyroidism treatment can relieve most or all of your symptoms through daily thyroid hormone pills, which replace the amount of hormone your thyroid is no longer making. Since hypothyroidism is not curable, you may need to be on medication for the rest of your life. 

Your health care provider will work with you to adjust the dose, since your hormone levels may change through the years. Periodic blood tests will monitor your thyroxine level to ensure you’re not getting too much thyroid hormone, which can cause hyperthyroidism

Hypothyroidism can affect or develop into other health issues if left untreated:
