Foods to avoid with hyperthyroidism and more


Hyperthyroidism is a condition in which the body secretes excessive amount of thyroid hormone. This problem is also called as overactive thyroid and it is a major cause of various problems like increased rate of metabolism, heart palpitations, insomnia, anxiety, changes in the menstrual cycle, goiter, weight loss, weight gain, troubled appetite, and many more. There are three major forms of hyperthyroidism, namely, graves disease, secondary hyperthyroidism, and toxic nodular goiter.When a person is diagnosed with hyperthyroidism, he/she is probably prescribed with various iodine supplements, thyroid depressive medications, thyroid hormone replacement therapy and surgery in severe cases. In all cases of hyperthyroidism, the patients need to be very careful about the kind of food that they are consuming. The health care provider and dietitian mostly provide them a well-balanced diet plan to speed up the recovery. However, check the following list of foods you should avoid if you have hyperthyroid.

This flour is difficult to digest and it has extremely low nutritional value. Food products that are made using refined flour are heavy on the digestive system with a high glycemic index. As we all know, foods with a high glycemic index are harmful to the blood sugar levels and hormones. It is the reason why one should replace refined flour with whole grain food items. It means, food items like white bread, snacks, cereals, and pasta that are made using refined flour need to be replaced by products like wheat bread, whole grain bread, brown rice, quinoa, barley, and other whole grain products. However, do not forget to consult your dietitian before making any major dietary changes in your daily diet.

2. Refined sugar

Refined sugarSimilar to refined flour, refined sugar and the products made using it should be cut down. Along with refined sugar, you also need to cut back on the types of sugar like cane sugar, dextrose, fructose, corn syrup, maple syrup and other types of added sugars. Sugar adds up to the calorie count and glycemic index of the food and slows down the pace of the recovery from overactive thyroid or hyperthyroidism.

Another disadvantage of having sweet and sugary foods is that it satiates the hunger faster and leaves no room for other healthy food items like vegetables and fruits that are actually beneficial. It is the reason why one should stay away from various sweets like jams, jellies, candy, pastries, cakes, frozen yogurts, carbonated soft drinks, canned fruit juices, cookies, and all the other foods that contain added sugar and any of its types.  Replace sugary foods with healthy no added sugar snacks.

The thyroid gland stores the minerals which are required during synthesizing the thyroid hormones. The food that you consume daily has iodine compounds in them. The salt that you use in your food is a rich source of iodine for your body. Potatoes, dairy products like milk, cheese, cranberries, organic yogurt, sea vegetables are all rich sources of iodine in your diet.

For pregnant women, the intake should be two hundred and ninety micrograms daily. Reducing the consumption of iodized salt and also iodine rich foods is a good preventive measure against hyperthyroidism.

2. Avoid excess hormone medication

There are many individuals who suffer from hypothyroidism, a condition in which thyroid glands produce less thyroid hormone. They have to take thyroid hormone medication to maintain the balance of thyroid hormone. The hyperthyroidism which occurs due to the medication being too high is known as factitious or doctor induced hyperthyroidism. Many people also take this medicine for losing weight. For such individuals, it is essential to reduce the dose of thyroid hormone medication and this will help prevent hyperthyroidism.

3. Prevent Grave’s disease


One of the major causes of hyperthyroidism in individuals is Grave’s disease. This is an autoimmune disorder which leads to an overactive thyroid gland. An abnormal immune system response causes an individual’s thyroid gland to produce excessive thyroid hormone. Double vision, goiter, menstrual irregularities are all symptoms of the disease. Whenever an individual experiences any such physical problems, he/she should consult a doctor and seek treatment. This will help in preventing hyperthyroidism, which is generally an off shoot of Grave’s disease.

In order to prevent hyperthyroidism, individuals should seek medical attention whenever they encounter an inflamed thyroid gland.

5. Treat toxic nodular goiter in time

hypothyroidismIn elderly people, often the presence of a toxic nodular goiter may lead to hyperthyroidism. This happens when one or two tumors in the thyroid gland produce excess hormone. This excess production leads to hyperthyroidism in the individual. To prevent this, an individual should consult the doctor at the earliest when they find any irritation in their thyroid which may be caused due to the tumors present there.

This will help you get rid of the unwanted tumor and also help in preventing thyroid problems arising from it.

Cigarette smokers are also more prone to getting affected with Grave’s disease (which also leads to hyperthyroidism) and treatment prescribed will also have less effect than on any other individual without this habit. It is, therefore, essential for individuals to curb this habit not only for the overall betterment of their health but also for avoiding diseases like hyperthyroidism. Passive smoking is also considered harmful for the thyroid glands. Individuals should consult their doctors for techniques to stop their smoking habit.
