Is Metformin Good for Hypothyroidism? (Expert Answer)

Short Answer: Metformin is not good for hypothyroidism. Because it has no beneficial ingredients for the condition and it can negatively affect thyroid hormone levels.

Hypothyroidism is a condition that affects your thyroid gland.

In hypothyroidism, your body produces an insufficient amount of thyroid hormones.

This can lead to various health problems, such as fatigue, weight gain, and increased sensitivity to cold.

One of the key factors in managing hypothyroidism is diet.

What you consume can affect your thyroid hormone levels, which can impact your hypothyroidism symptoms and overall health.

To effectively manage hypothyroidism, you should consume selenium and tyrosine rich foods like sunflower seeds, Brazil nuts, and meats and avoid iodine-rich foods like iodized salt, soy, and cruciferous vegetables.

Now, Metformin is a medication commonly used to treat type 2 diabetes.

People usually take it orally in tablet form.

Metformin is not recommended for hypothyroidism because it contains no nutritional ingredients and may interfere with thyroid hormone levels.

Metformin use has been linked with a 55% increased risk of low TSH levels in patients with treated hypothyroidism, compared with the use of sulfonylurea.

A typical dose of Metformin can range from 500 mg to 1000 mg, taken with meals.

Metformin can negatively affect hypothyroidism by potentially lowering TSH levels, which is not desirable as it could lead to subclinical hyperthyroidism.

Furthermore, Metformin is a biguanide and biguanides are not good for hypothyroidism.

Because, they can decrease the amount of thyroid-stimulating hormone (TSH), which is necessary for thyroid hormone production.

That’s why I suggest you limit your Metformin intake if you have hypothyroidism to prevent potential reduction in TSH levels.

Stick to thyroid hormone therapy as prescribed by your doctor to minimize risks associated with low TSH levels.

Also, you shouldn’t take Metformin if you are suffering from hypothyroidism to prevent low TSH levels.

Because it can interfere with your thyroid hormone therapy.

You can buy Metformin online as well as offline.

To buy it online, there are many brands and marketplaces to choose from.

But as a medication, it’s important to follow your doctor’s prescription and purchase the brand that your healthcare provider recommends.

Finally, remember, maintaining a healthy lifestyle, including a balanced diet, regular exercise, stress management, and essential medical care is key to managing/dealing with hypothyroidism effectively.

I always recommend my hypothyroidism patients to follow a hypothyroidism-friendly diet to improve their overall well-being, and enjoy a longer and healthier life.
