When people talk about metabolism, they often think of how quickly the body burns calories. But metabolism is much more than that.
It includes all the chemical processes that keep us alive—like turning food into energy and repairing our cells.
One condition that affects metabolism is hypothyroidism. This is when the thyroid gland, located in the neck, doesn’t make enough thyroid hormones. These hormones, mainly T4 (thyroxine) and T3 (triiodothyronine), help control how fast your body works. They affect your heart rate, body temperature, and how quickly you burn calories.
So, when these hormones are low, your whole body slows down. You may feel tired, gain weight, feel cold often, or have constipation and dry skin. It’s like your body’s engine is running on low power.
Because it changes the way the body turns food into energy, hypothyroidism can be considered a metabolic disorder. Metabolic disorders affect how your body handles chemical reactions, especially those linked to energy use. Hypothyroidism clearly fits this description.
Many things can cause hypothyroidism. One of the most common is an autoimmune disease called Hashimoto’s thyroiditis, where the body’s immune system mistakenly attacks the thyroid. Other causes include certain medications, radiation treatments, and problems with the pituitary gland.
To find out if someone has hypothyroidism, doctors usually do a blood test to check hormone levels. If your TSH (thyroid-stimulating hormone) is high and your T4 is low, it usually means your thyroid is underactive.
Treatment usually involves taking a daily pill of synthetic thyroid hormone. This replaces what your body is missing and helps your metabolism return to normal. But finding the right dose can take time. Doctors check your blood regularly and adjust the dose as needed.
Hypothyroidism doesn’t just affect energy and weight. It can also raise cholesterol levels, affect heart health, and even impact your mood. That’s why it’s important to see it as more than just a thyroid problem—it’s a condition that affects the entire body.
Scientists continue to study hypothyroidism to better understand its links to other health issues and how best to treat it. These studies help highlight how important the thyroid is to our overall health.
In summary, hypothyroidism is more than just feeling tired or gaining weight. It slows down many processes in the body and is, indeed, a metabolic disorder. Knowing this can help people understand their symptoms and seek the right treatment, showing just how connected all parts of the body truly are.
