Sweet taste in mouth thyroid

Thyroid hormone imbalance can create a lot of impairment in the mouth. These include the emergence of hormonal diseases and disorders, toxic influences from external sources, and inherited deficiencies in the production of hormones in the body.

Why do I feel a permanent sweet taste in mouth?

The taste buds on our tongue can detect five different types of flavors: sweetness, bitterness, saltiness, sourness, and ‘umami’ which is a sort of balanced flavor. So, when you eat sweets, the taste buds immediately let you know you are eating something sweet. The taste buds normally retain any flavor for a while, if not washed or brushed away from the tongue. However, it is uncommon to feel a lasting sweet taste in your mouth, as this could be an indication of a thyroid problem or worse.

Although research is still underway to determine the specific cause or causes of this phenomenon, it is certain that there are several known causes and conditions that may result in a permanent sweet taste in the mouth.

Some of the major reasons behind a constant sweet taste in the mouth are:

  • Thyroid problems:

A sweet taste in mouth might be caused by thyroid problems. The thyroid gland is responsible for controlling the metabolism by transforming the extra protein into blood sugar. This lets the body switch to burning fat as a source of energy. Hence, an insufficient blood sugar level may cause a sweet taste in mouth.

  • Pregnancy –

A woman’s body undergoes severe changes as far as metabolism and hormones are concerned. Many women complain of a constant sweet or metallic taste developing in their mouths, especially during the first few months of pregnancy.

  • Neurological disorders:

Several neurological problems, such as strokes and seizures, have been linked to the disruption of the sensory system, which causes the sweet taste in the mouth.

Diabetes is a common cause of developing a permanent sweet taste in mouth. As the insulin level in the blood sugar gets out of control, it can result in a distinct sweet taste in mouth, along with other symptoms, such as blurred vision, excessive thirst, frequent urination, and constant fatigue.

  • Infections –

Several bacterial and viral infections, especially those that attack the olfactory (sense of smell) and sensory systems, can result in a permanent sweet taste in mouth.

Hypothyroidism vs Hyperthyroidism


Hypothyroidism is a common disease in which the thyroid gland fails to produce enough hormones. The symptoms include weight gain and fatigue. Sufferers tend to develop wrinkled skin and have higher cholesterol levels than normal, as well as joint aches.


Hyperthyroidism is a condition caused by an overproduction of thyroid hormone. It comes with a range of unpleasant symptoms, including weight loss, highly accelerated metabolism, and irregular heartbeats.
