Causes & Symptoms of Hypothyroidism

The thyroid is a small, butterfly-shaped gland that drapes across the front of your windpipe.

If you place your fingers on the sides of your Adam’s apple and swallow, you’ll feel your thyroid gland sliding under your fingers.

It releases thyroid hormone, which controls the growth and metabolism of essentially every part of your body.

The pituitary, a tiny gland in the middle of your head, monitors your physiology and releases thyroid-stimulating hormone (TSH). TSH is the signal to the thyroid gland to release thyroid hormone.

Sometimes TSH levels increase, but the thyroid gland can’t release more thyroid hormone in response. This is known as primary hypothyroidism, as the problem begins at the level of the thyroid gland.

Other times, TSH levels decrease, and the thyroid never receives the signal to increase thyroid hormone levels. It is called secondary hypothyroidism.

Hypothyroidism, or “low thyroid,” can cause a variety of signs and symptoms. This article will help you recognize and understand these effects.

 

  1. Weight Gain:

Unexpected weight gain is another common symptom of hypothyroidism.

Not only are low-thyroid individuals moving less — they’re also signaling their livers, muscles and fat tissue to hold on to calories.

When thyroid levels are low, metabolism switches modes. Instead of burning calories for growth and activity, the amount of energy you use at rest, or your basal metabolic rate, decreases. As a result, your body tends to store more calories from the diet as fat.

Hypothyroidism signals the body to eat more, store calories and burn fewer calories. This combination leads to weight gain.

 

  1. Fatigue:

One of the most common symptoms of hypothyroidism is feeling worn out. Thyroid hormone controls energy balance and can influence whether you feel ready to go or ready to nap. Those with high levels of thyroid hormone feel nervous and jittery. In contrast, people with low thyroid feel exhausted and sluggish.

In one study, 138 adults with hypothyroidism experienced physical exhaustion and reduced activity. They also reported low motivation and feeling mentally tired

 

 

  1. Hair Loss:

Like most cells, hair follicles are regulated by thyroid hormone.

Because hair follicles have stem cells that have a short lifespan and rapid turnover, they are more sensitive to low thyroid levels than other tissues.

Low thyroid hormone causes hair follicles to stop regenerating, resulting in hair loss. This will typically improve when the thyroid issue is treated.

 

 

  1. Menstrual Irregularities:

Both irregular and heavy menstrual bleeding is linked to hypothyroidism.

One study showed that about 40% of women with low thyroid hormone experienced increasing menstrual irregularity or heavy bleeding in the last year, compared to 26% of women with normal thyroid levels

 

  1. Constipation:

Low thyroid levels put the brakes on your colon.

According to one study, constipation affects 17% of people with low thyroid hormone, compared to 10% of people with normal thyroid levels

While constipation is a common complaint in patients with hypothyroidism, it’s uncommon for constipation to be the only or most severe symptom.

 

  1. Changes in Skin Texture:

Like hair follicles, skin cells are characterized by rapid turnover. Therefore, they are also sensitive to losing growth signals from the thyroid hormone.

When the normal cycle of skin renewal is broken, the skin may take longer to regrow.

This means the outer layer of skin has been around longer, accumulating damage. It also means that dead skin may take longer to shed, leading to flaky, dry skin.

 

 

  1. Diabetes:

Hyperthyroidism is typically associated with worsening glycemic control and increased insulin requirements. There is underlying increased hepatic gluconeogenesis, rapid gastrointestinal glucose absorption, and probably increased insulin resistance. Indeed, thyrotoxicosis may unmask latent diabetes.

 

  1. Depression:

Hypothyroidism is linked to depression. The reasons for this are unclear, but it might be a mental symptom of an overall decrease in energy and health.

64% of women and 57% of men with hypothyroidism report feelings of depression. About the same percentage of men and women also experience anxiety

 

  1. Infertility:

Low levels of thyroid hormone can interfere with the release of an egg from your ovary (ovulation), which impairs fertility. In addition, some of the underlying causes of hypothyroidism — such as certain autoimmune or pituitary disorders — may impair fertility.

 

The thyroid is a crucial gland in our body and considering these various factors that it can have an impact on Dr. Ashish Kale – An IVF Specialist in Pune recommends not only his patients but others as well to not ignore these symptoms and have a close watch on it and take the necessary precautions.
