Hypothyroidism, or underactive thyroid, is often associated with weight gain. The cause and the amount of weight gain vary among individuals, depending on the severity of the condition as well as dietary and lifestyle habits. If you've gained weight as a result of hypothyroidism, proper treatment for your condition in addition to improved dietary and lifestyle measures can help you manage your weight healthfully.
Metabolism
Since your basal metabolic rate (BMR) is elevated, modest weight gain is a common symptom of hypothyroidism. However, according to the American Thyroid Association (AATA), BMR is less affected by hypothyroidism than other thyroid conditions, such as hyperthyroidism, or overactive thyroid. Though doctors previously used BMR as a primary indicator of hypothyroidism, metabolic factors are now considered but one potential aspect of the condition. Metabolism shifts and weight gain associated with hypothyroidism are generally modest.
Primary Causes
Weight gain associated with hypothyroidism is often the result of water and salt accumulation in the body. The weight gained due to these conditions is modest, rarely exceeding 5 to 10 lb. If weight gain exceeds this amount, it is likely due to other factors in addition to the disorder, such as lack of inactivity or consuming more calories than you burn on a regular basis. Lethargy is a common symptom of hypothyroidism, so you may become less active prior to treatment, which may also contribute to weight gain.
Weight Management
Healthy weight management is important when you have hypothyroidism, as being overweight increases your risk for diabetes, heart disease and other serious health conditions. According to the AATA, weight gain that results from metabolic and hormonal changes generally reduces once hypothyroidism is properly treated. Symptoms of lethargy and exhaustion often dissipate once the condition is treated as well, making physical activity a more feasible option.
If you've been diagnosed with hypothyroidism and have sought effective treatment, gradually incorporate regular physical activity into your lifestyle. The American Dietetic Association recommends a healthy, balanced diet, rich in fruits, vegetables and whole grains, and low in saturated fats and processed foods, in addition to regular physical activity as an optimum way to manage weight healthfully. For best results, seek guidance and supervision from a qualified medical or dietary professional who can assist you in the weight loss process.
