Diabetes and thyroid disease are both endocrine. Or hormone, problems. When thyroid disease occurs in someone with diabetes, it can make blood glucose control more difficult.

The thyroid is a butterfly shaped gland in your skin. It regulates your body’s metabolism, the processes of using and storing energy, by releasing a substance called thyroid hormone. If it produces too much thyroid hormone, your metabolism quickens (hyperthyroidism), too little and your body functions slow down (hypothyroidism).

Effects on Diabetes Hyperthyroidism.

When your metabolism quickens, your medicines go through your body quicker. Your blood glucose level may rise because your body long enough to control it.

Hyperthyroidism and low blood glucose can be hard to tell apart. If you are sweating and having tremors from hyperthyroidism, you may think you have low blood glucose and eat extra food, causing your blood glucose to rise. Using your glucose meter to verify low blood glucose levels can help you avoid this problem.

Hypothyroidism. When your metabolism slows, your blood glucose level may drop because your diabetes medicine doesn’t pass through your body as quickly as usual and so stays active longer. In hypothyroidism, it is often necessary to reduce your dose os diabetes medicines to prevent low blood glucose.

If You Think Have Thyroid Disease…

Tell your heath care provider about any symptoms you have. A physical exam and simple blood test can identify hyper- or hypothyroidism.

If you have hyperthyroidism, medicines and other treatments can help slow your metabolism by controlling the release of thyroid hormone. If you have hypothyroidism, your health care provider can prescribe thyroid hormone pills to speed up your metabolism. You will need follow-up blood tests every few months to adjust your dosage of thyroid hormone.
