Hyperthyroidism Vs Hypothyroidism: How Are They Different?

A part of the endocrine gland, the thyroid is a butterfly-shaped gland that generates hormones. The thyroid produces two hormones namely - Triiodothyronine (T3) and Thyroxine (T4), that regulate metabolism, aid in the proper functioning of the heart, brain, and other organs. They also have a significant impact on almost every cell of our body.

The pituitary gland controls and regulates the thyroid. The thyroid also produces a hormone called Thyroid-stimulating hormone (TSH) that tells the thyroid to generate more T3 and T4. When any portion of the thyroid gets damaged, the thyroid gland starts producing either too little or too much T3 and T4. This could result in symptoms that affect the entire body.

Let’s get to know about Hyperthyroidism and Hypothyroidism, two conditions that happen when thyroid hormone fluctuates.


Hyperthyroidism occurs when your body produces too much of the thyroid hormones, thyroxine (T4) and triiodothyronine (T3), causing your body to become hyperactive.

Signs and symptoms of Hyperthyroidism include:

  • Weight Loss
  • Increased Appetite
  • Sensitivity To Heat
  • Fast, Irregular Heartbeat (Palpitations)
  • Warm, Moist Skin
  • Frequent Bowel Movements
  • Vision Changes
  • Thin, warm, and moist skin.

Hyperthyroidism can be cured and reversed. Effective treatments include antithyroid medications, radioactive iodine, and surgery.


  • Graves' Disease
  • Hyperfunctioning Thyroid Nodules
  • Thyroiditis
  • Overmedication
  • Abnormal iodine levels
  • Pregnancy (in certain cases)
  • Hereditary


Hypothyroidism occurs when your thyroid gland is unable to produce enough hormones to keep you healthy and make your body function well. The thyroid gland is in charge of your entire body's metabolism. In hypothyroidism, the thyroid gland's hormone production slows the metabolism rate, contributing to fatigue and weight gain.

Some of the signs and symptoms of Hypothyroidism include:-

  • Weight Gain
  • Constipation
  • Dry Skin
  • Puffy Face
  • Hoarse Voice
  • Tiredness and weakness

Hypothyroidism is often a lifelong condition requiring supplementation of thyroxine hormone. However, with the help of medications, we can control the disease and alleviate the symptoms.


  • Autoimmune Disease
  • Surgical Removal of Thyroid Gland
  • Radiation Treatment
  • Congenital Problem
  • Thyroiditis
  • Certain Medications
  • Abnormal Iodine Levels
  • Pituitary Gland Damage
  • Certain Uncommon Diseases & Conditions

Having an underactive thyroid (Hypothyroidism) can decrease or slow down your bodily functions. Hyperthyroidism, on the other hand, may cause you to have more energy rather than less. Hormone levels are the most common and typical distinction between the two disorders. Hormone levels drop as a result of hypothyroidism. Hormone production rises as a result of hyperthyroidism.

Both hypothyroidism and hyperthyroidism are common diseases. Each condition has its own set of symptoms and complications that can interfere, and affect the quality of one's life. While few symptoms are simple and may not impact much, few symptoms are potentially life-threatening and if immediate medical intervention and timely treatment are not given it could lead to serious problems.
