The Link Between Fatigue and Thyroid Disorders

There are several causes of fatigue among women. And too little production of the thyroid hormone thyroxine or hypothyroidism is most often to blame for fatigue in women over 50. Besides fatigue, menopause and too little thyroxine production share symptoms such as hot flashes, hair loss, and depression. That’s why hypothyroidism is often mistaken for menopause.

What are thyroid disorders?

Fatigue can result from overactive or underactive thyroid glands. These problems mainly affect women with a family history of thyroid disorders or those with autoimmune issues like diabetes 1.

That said, hypothyroidism is one of the significant causes of fatigue among older women. This condition occurs when your body releases too little of the thyroid hormone thyroxine. And because your thyroid hormone controls your metabolism, low levels of this hormone can affect your bones, heart, muscles, and cholesterol.

Also known as underactive thyroid, hypothyroidism is ten times more common in women than men. And it is estimated about 12.5 percent of women may be affected by this thyroid disorder. Unfortunately, most women miss hypothyroidism because they attribute its signs to menopause or aging. 

On the other hand, people with hyperthyroidism produce excessive amounts of the thyroid hormone thyroxine. As a result, its symptoms include sweating, weight loss, rapid heart rate, and sometimes eye issues.

It’s essential to get help because fatigue can affect your day-to-day life. For example, most women with hypothyroidism can’t function without a nap during the day, which interferes with other essential duties.

Knowing the underlying issues can help you understand what is ailing you. Luckily, a comprehensive blood test can help you with your diagnosis.

Why hypothyroidism is rare in women

First, as mentioned, hypothyroidism and menopause share similar symptoms. They include weight gain, fatigue, loss of libido, and feeling cold — especially in your hands and feet. That’s why most specialists misdiagnose hypothyroidism as menopause or natural aging.

Another misdiagnosis is the failure to do a comprehensive lab test. A full-scale test requires the lab to test all six thyroid markers. But sometimes, the lab may test only one or two markers which may give inconclusive results.

Bottom line; you require proper diagnosis if your fatigue doesn’t go away after adequate exercise, rest, healthy foods, or stress management strategies.

Coping with hypothyroidism and fatigue

There are several strategies that people with hypothyroidism can use to cope with fatigue. Excess fatigue is often accompanied by other emotions like anger, frustration, depression, or sadness. 

Remember, hypothyroidism affects women in different ways. Some get it suddenly, while others call it gradually, meaning they will react differently. Either way, there are ways to live with thyroid hormone disorders.

Emotional

Living with a lifelong condition like hyperthyroidism or hypothyroidism is not easy. It’s normal to undergo a range of emotions, from frustration to sadness. But be aware of the signs of onsetting depression or anxiety. 

Also, you are advised to talk to a therapist because trying to sort out your emotions can be overwhelming. Therapists, yoga, and mindfulness, among other stress management techniques, can improve your work-life-relationships balance.

Physical 

Inactive habits and an unhealthy diet can also influence your emotions. Weight gain is primarily a significant issue when it comes to hypothyroidism. People often find it difficult to lose weight even after medication. So, it’s advisable to exercise and maintain a healthy diet. 

Medical 

Try to follow up with your healthcare provider and learn more about your condition. Also, do regular thyroid blood tests to know the optimum levels for your health (ask your specialist).

Social help in managing thyroid disorders

Your loved ones can help you stay on top of your thyroid wellness. Go on a date with a partner, meet a friend, or join a thyroid support group. However, don’t shut out people who care about you or go at it alone.

With love and care, hypothyroidism and fatigue can be managed.
