How Does My Thyroid Work

The thyroid gland is a small, butterfly-shaped organ located in the front of your neck just under the voice box . Picture the middle of the butterflys body centered on your neck, with the wings hugging around your windpipe . The main job of the thyroid is to control your metabolism. Metabolism is the process that your body uses to transform food to energy your body uses to function. The thyroid creates the hormones T4 and T3 to control your metabolism. These hormones work throughout the body to tell the bodys cells how much energy to use. They control your body temperature and heart rate.

When your thyroid works correctly, its constantly making hormones, releasing them and then making new hormones to replace whats been used. This keeps your metabolism functioning and all of your bodys systems in check. The amount of thyroid hormones in the bloodstream is controlled by the pituitary gland, which is located in the center of the skull below the brain. When the pituitary gland senses either a lack of thyroid hormone or too much, it adjusts its own hormone and sends it to the thyroid to balance out the amounts.

If the amount of thyroid hormones is too high or too low , the entire body is impacted.

Reproductive Changes In Women Could Mean You Have Low Thyroid

Women are at an increased risk for developing thyroid disease. Women are also more likely to develop thyroid conditions after pregnancy and following menopause.

Women may experience a change in their menstrual cycle if their thyroid function is off, says Dodell. Not only might you experience irregularities in your cycle, but hypothyroidism may also cause periods that are much heavier than normal.

Women who are trying to conceive may have difficulties getting pregnant. Therefore, women who are trying to get pregnant or are planning to try and get pregnant in the near future should have their thyroid levels checked, Dodell explains. We also monitor women who are being treated for hypothyroidism closely during pregnancy, since the dose of medication may need to be adjusted.

Menopausal women may experience worsening symptoms. Early menopause is a side effect of hypothyroidism this occurs when the onset of menopause is before age 40.

Whats The Connection Between Hypothyroidism And Weight Gain

Your thyroid is responsible for many of your bodys daily functions, including metabolism, organ function, and temperature control. When your body doesnt produce enough thyroid hormone, all of these functions can slow down.

If your thyroid gland doesnt function properly, your basal metabolic rate may be low. For that reason, an underactive thyroid is commonly associated with weight gain. The more severe the condition is, the greater your weight gain is likely to be.

The typical amount of weight gain isnt very high, though. Most people will gain somewhere between 5 and 10 pounds.

Properly treating the condition can help you lose any weight you gained while your thyroid levels were uncontrolled. However, keep in mind that thats not always the case. Symptoms of underactive thyroid, including weight gain, develop over a long period of time.

Its not uncommon for people with low thyroid hormone levels to lose no weight after theyre treated for the condition. That doesnt mean the condition isnt being properly treated. Instead, it may indicate that your weight gain was the result of lifestyle choices rather than low hormone levels.
