Dietary advice for hyperthyroid patients undergoing treatment
People who are hyperthyroid tend to lose weight because their body’s metabolic rate is faster than normal. In the body’s effort to compensate for burning fuel (food) faster, the appetite and, consequently, food intake, increase. This varies from person to person, sometimes taking the form of larger food portions or more between-meal snacks. Also, there is often a preference for more sweets. If consumption does not keep up with the increased metabolism, weight loss occurs. (It is also possible to increase intake so much that a weight gain occurs.)
Whatever the therapy, treatment of hyperthyroidism is aimed at lowering the activity of the thyroid gland. Thyroid hormone levels in the blood will then decrease, and the body responds by lowering the rate at which fuel is consumed (metabolism). When recovery from hyperthyroidism occurs and the metabolism becomes normal, the total amount of food needed will decrease.
Appetite control, unfortunately, often lags behind the body’s metabolic adjustments. Therefore, appetite and food intake frequently may continue as before and be greater than the body’s actual new requirement. The result may be a tendency to gain weight. This weight gain is not an inevitable result of the cure of hyperthyroidism but simply a temporary mismatch between the appetite, food intake, and metabolic rate. Appetite is hard to control, and recovering patients may need to take action in limiting their food intake.
As treatment of hyperthyroidism takes effect and symptoms are relieved — and this happens gradually — sensible intake will help minimize any tendency to gain weight. Decreasing sugar and fat while eating more high fiber carbohydrate foods (for example, whole grain products, including breads, cereals, and potatoes) will help control the tendency to gain weight. Protein should be an important part of at least two meals each day. The usual semi-sedentary person should keep intake to about 1000 to 1500 calories, at least until the hyperthyroidism is completely cured and weight stabilizes. Protein should be about 12 percent of this total. Check your weight weekly to keep alert to any tendencies to gain.
The above is part of the instructions given to patients undergoing treatment for hyperthyroidism in an effort to help them stabilize their weight and avoid weight gain as they get well.
