Does Drinking Water Help Hyperthyroidism?

If you have been diagnosed with hyperthyroidism, you may be well aware of the various changes and challenges that come with it. From weight loss and increased heart rate to anxiety and tremors, hyperthyroidism can have a significant impact on your daily life. While there are various treatment options available, have you ever considered the role of water in managing this condition?

The Link Between Water and Hyperthyroidism

Water is an essential element for our body’s proper functioning. It has multiple roles, such as regulating body temperature, transporting nutrients and oxygen to cells, removing waste, and facilitating digestion. When it comes to hyperthyroidism, drinking enough water is crucial due to its role in maintaining the body’s balance and aiding in recovery.

Hyperthyroidism is a condition characterized by an overactive thyroid gland, which produces too much of the thyroid hormones T3 and T4. This can lead to increased sweating and loss of body fluids, leaving hyperthyroid patients at a high risk of dehydration. Dehydration can further worsen this condition, causing serious health complications.

How Does Drinking Water Help?

By staying hydrated, you can alleviate some of the symptoms associated with hyperthyroidism. Water can help in the following ways:

1. Regulating Body Temperature

As mentioned earlier, water helps regulate body temperature. When you have hyperthyroidism, your body’s metabolism increases, leading to an increased body temperature. Drinking enough water helps the body cool down and maintain a stable body temperature, especially during hot weather.

2. Replenishing Lost Fluids

Hyperthyroidism can cause excessive sweating and loss of body fluids, leading to dehydration. Drinking enough water helps replenish these lost fluids and maintains the body’s fluid balance. This, in turn, can help reduce symptoms such as dizziness and fatigue, which are often associated with dehydration.

3. Aiding in Digestion

An overactive thyroid gland can also speed up the digestive process, causing frequent bowel movements. This can lead to dehydration and electrolyte imbalances. Drinking water can help keep your digestive system functioning normally and prevent constipation, which is also a common symptom of hyperthyroidism.

4. Flushing Out Toxins

Water is essential for getting rid of toxins that can accumulate in the body due to hyperthyroidism. Drinking enough water helps flush out these toxins, keeping your body clean and healthy.

5. Reducing Heart Rate

Hyperthyroidism can increase your heart rate, making you feel anxious and jittery. Staying hydrated can help reduce your heart rate and calm your nerves, reducing anxiety and tremors.

How Much Water Should You Drink?

Now that you know why water is important for managing hyperthyroidism, the next question is, how much water should you drink? The recommended daily intake of water for adults is 2.7-3.7 liters, with the exact amount depending on factors such as age, gender, and physical activity. However, if you have hyperthyroidism, it is recommended to drink around 8-10 glasses of water every day, and more if you engage in physical activities that cause sweating.

Other Tips for Staying Hydrated

Drinking plain water is the best way to stay hydrated. However, if you find it challenging to drink enough water, here are a few tips that can help:

1. Add Flavor

If plain water doesn’t appeal to you, try adding a slice of lemon or some fruits to give it a refreshing flavor. You can also try infused water with herbs such as mint or basil.

2. Keep Water Handy

Make it a habit to carry a water bottle with you, whether you are running errands, working, or exercising. This will help remind you to drink water throughout the day.

3. Eat Water-Rich Foods

In addition to drinking water, you can also increase your water intake by consuming water-rich foods such as fruits (watermelon, cantaloupe, strawberries) and vegetables (cucumber, lettuce, celery).


Drinking sufficient water is crucial for maintaining good health, and even more so if you have hyperthyroidism. Water helps regulate body temperature, replenish lost fluids, aid in digestion, flush out toxins, and reduce heart rate. Therefore, it is essential to stay adequately hydrated by drinking enough water and incorporating other healthy habits.
