What are the contraindications for hypothyroidism patients taking levothyroxine tablets for a long time?

Hypothyroidism, referred to as hypothyroidism, is a systemic hypometabolic syndrome caused by insufficient synthesis and secretion of thyroid hormones or biological effects, and it is one of the common clinical diseases in endocrinology. Many patients with hypothyroidism go to the hospital for treatment, and doctors will prescribe levothyroxine tablets for patients. L- thyroxine tablets are the same as thyroxine naturally secreted by thyroid gland, which is converted into T3 as an endogenous hormone in peripheral organs, and then plays its specific role by combining with T3 receptor, which is mainly used to treat hypothyroidism and other diseases in clinic.

Is there any taboo to eat Perrin?

In fact, this question should not only consider the drug itself, but also combine the characteristics of hypothyroidism to analyze and answer. The analysis here is as follows:

1. Avoid taking with food containing metal ions such as iron, aluminum or calcium.

L- thyroxine itself is easily influenced by some foods and supplements. Taking it together with foods or drugs containing metal ions such as iron, aluminum or calcium will reduce the absorption of L- thyroxine. These metal ions mainly exist in meat, vegetables, milk and eggs. In addition, strong tea, coffee, soybeans and high-fiber foods will interfere with the absorption of Eupatorium odoratum and should be avoided. Therefore, the instructions suggest taking levothyroxine on an empty stomach once a day and half an hour before breakfast. If it is impossible or inconvenient to do so, you can take Eupatorium adenophorum before going to bed.

2. Avoid a lot of iodine-containing foods.

Iodine is the raw material for the synthesis of thyroxine, and iodine deficiency can lead to clinical symptoms of goiter and hypothyroidism. Although it is necessary to properly supplement iodine in the diet of hypothyroidism patients, attention should be paid to avoid excessive consumption of foods with high iodine content, such as kelp, laver, seafood, etc., because iodine intake synthesizes thyroxine, which has an additive effect with Eupatorium, and it is easy for patients to turn into hyperthyroidism.

3. Use foods that cause goiter with caution.

Such as cassava, walnuts, Chinese cabbage, cabbage, radish, strawberries, peanuts and other foods, all contain substances that cause goiter, which can affect the synthesis of thyroid hormones and cause temporary hypothyroidism, but these substances can be destroyed after heating, so it is recommended that the above foods be cooked before eating.

4. Add appropriate protein.

Studies have shown that thyroid function tends to be low at low protein. Moreover, after taking Perrin, the metabolic rate of the body will increase, and the consumption of protein will also increase, so patients with hypothyroidism should appropriately supplement protein. Someone asked, can hypothyroidism patients eat protein powder? Protein powder, which is mostly purified from plant protein, is an excellent protein supplement. Patients with hypothyroidism can also eat it as long as they eat it in moderation.

5. Limit the intake of triglycerides and cholesterol.

Patients with hypothyroidism are prone to hyperlipidemia and hypercholesterolemia due to slow metabolism and decreased triglyceride and cholesterol metabolism. In addition, studies have shown that high triglyceride diet can induce hypothyroidism. Taking Eupatorium adenophorum while eating a high-fat diet will greatly reduce the efficacy and increase the risk of coronary heart disease, so it is necessary to limit the intake of triglycerides and cholesterol.

Due to the insufficient level of thyroid hormone in patients with hypothyroidism, clinical symptoms can be manifested as loss of appetite, decreased food intake and so on. Abdominal distension and constipation may also occur; And because of the reduction of heat production, the basal metabolic rate of patients will decrease. Therefore, from the perspective of nutritional therapy as a whole, the diet of hypothyroidism patients follows the principle of "high protein, high vitamin, high cellulose and low fat diet", while pursuing color, fragrance and taste in the cooking process to increase the appetite of patients; You can choose a small number of meals, and pay attention to provide a comfortable eating environment, eat more vegetables and fruits, drink about two to three liters of water every day, encourage hypothyroidism patients to exercise properly, and often carry out abdominal massage to promote intestinal peristalsis, reduce constipation and stimulate appetite.
