The thyroid gland is a butterfly-shaped structure located in front of the neck. Its role is to produce hormones that regulate metabolism and other body functions. However, if the thyroid gland produces abnormal amounts of hormones, one may experience several symptoms which include unwanted weight loss or difficulty of losing excess weight. Having said this, you have to know how the thyroid affects weight loss in men.
The thyroid gland produces hormones and these hormones circulate to the body and signal the cells to burn energy as stated by the American Association for Clinical Chemistry’s lab Tests Online. The main hormones usually produced by the thyroid gland are Triiodothyronine (T3) and Thyroxine (T4). The body controls the effects of T3 and T4 in combination with a product of the brain’s hypothalamus known as thyrotopin-releasing hormone. This hormone causes the pituitary gland to release another hormone called thyroid-stimulating hormone which in return this hormone triggers the production of T3 and T4 in the thyroid gland.
Basal Metabolic Rate and Thyroid
The thyroid gland is the one that regulates metabolism not only in men but also in women. According to the American Thyroid Association, metabolism is the rate of how quickly oxygen is used in the body. Basal Metabolic Rate (BMR) is the measurement of the metabolic rate taken while the body is at rest. Once the thyroid hormone levels change, the BMR either increases or decreases which can affect the metabolic processes in the body.
Hyperthyroidism and Weight
Hyperthyroidism is the excessive production of thyroid hormones in the body and according to the American Thyroid Association, this condition increases metabolism and possibly cause unwanted weight loss. In addition, the Medline Plus website noted several symptoms like it can increase the risk of poor muscle growth, slower healing and edema. It can also increase appetite which leads to an increased caloric intake. Other potential symptoms are heat intolerance, nervousness, irritability, heartbeat irregularities, sleeping difficulties and fatigue.
Hypothyroidism and Weight
Hypothyroidism is the condition where the thyroid gland produces insufficient amount of hormone which can decrease energy usage thus making one to gain weight and difficult to lose weight. Symptoms of hypothyroidism are slowed heart rate, muscle and joint pain, fertility difficulties, fatigue, cold intolerance and abnormal menstrual flow. The National Endocrine and Metabolic Diseases Information Service website mentioned that hypothyroidism contribute to high cholesterol so it suggests that people suffering from high cholesterol must have their thyroid checked as high cholesterol can lead to cardiovascular disease.
The Medline Plus website noted that 1 pound of fat is equivalent to 3,500 calories. One can achieve weight loss by controlling caloric intake or increasing calorie burn through physical activity. Increasing exercise and decreasing consumption of caloric foods can lead to a negative balance in the overall caloric intake which results to weight loss. In this case it will affect metabolism making it high or low thus it is hard to predict weight loss. If you suspect thyroid problems, visit your doctor at once for diagnosis and treatment.
