Underactive Thyroid is also known as Hypothyroidism.
People who have hypothyroidism can find it difficult to focus and to think clearly. This effect of hypothyroidism is known as thyroid brain fog.
Hypothyroidism occurs when the thyroid gland produces lower than normal levels of hormones. The hormones that are produced by the thyroid gland are responsible for the regulation of the metabolism. When the levels of thyroid hormones are too low because of an under active thyroid gland, the metabolic rate is slower than normal. This can cause symptoms such as fatigue, sleepiness and difficulty concentrating.
People who experience the hypothyroid brain fog find themselves unable to focus properly. Their mental clarity and function is affected by their condition. In some cases, the memory can also be affected by hypothyroidism. These symptoms are often more common and more severe in older patients with the condition.
The symptom of brain fog can affect the patient’s ability to work or study, and it can therefore have a serious impact on quality of life. Symptom is neither harmful nor dangerous, other than when it affects driving or operating machinery. Many people find that the effects of hypothyroidism on their cognitive function is one of the most upsetting symptoms that they experience. It can be particularly worrying before an explanation has been found. It does not cause mental deterioration or loss of intelligence, despite the fact that it can be extremely unpleasant.
Brain fog can also be caused by other conditions, particularly those that relate to depression and anxiety. Experiencing this symptom may not necessarily indicate hypothyroidism, but it is often associated with thyroid disorders.
Brain fog can be a worrying and distressing symptom of hypothyroidism, but it is usually temporary and harmless. This symptom will often disappear once hypothyroidism treatment is begun, although it can still be a problem for some patients.
Dietary supplements such as B vitamins may help, although it is important to avoid taking supplements that contain calcium or iron as these can affect the absorption of the medication that is used to treat hypothyroidism. Regular exercise can also help to reduce the brain fog that is caused by hypothyroidism.
