Symptoms of an underactive thyroid gland: a detailed list

What are the symptoms of an underactive thyroid gland? Does this health problem have specific symptoms that are easy to distinguish? And what do you need to know about it? Details in the following article.

Known as idle thyroid (Hypothyroidism - Underactive thyroid disease) and many others, such as the designations of hypothyroidism, and the laziness of the thyroid gland. This disease occurs when the thyroid gland is unable to produce enough of its natural hormones, which can lead to symptoms of an underactive thyroid gland. So what are these symptoms? The answer is in the following:

Symptoms of an underactive thyroid gland in adults

Here is a list of the most notable:

1. Changes in mood and memory 

An underactive thyroid gland that the affected person has not undergone the necessary treatment may cause some neurological and psychological changes, such as:

Sadness and bad mood.
Depression.
Malfunctions in memory functions.
anxiety.
Decreased levels of focus and alertness.
Slow in thinking and speaking.
Apathy, loss of desire to do things that the patient was previously fond of.

The reason for the above symptoms is that the thyroid hormones that are less produced in the bodies of people with hypothyroidism are important hormones to ensure the normal functioning of the brain, and low levels of these hormones may lead to changes that are often temporary in the structure of the brain.

2. Cardiovascular problems 

One of the symptoms of an underactive thyroid gland is the emergence of some problems in the circulatory system, such as the following:

slow heartbeat (bradycardia) 

Low levels of thyroid hormones may negatively affect the heart rate, triggering bradycardia, a condition that may lead to the emergence of many complications, some of which may be serious, such as hypotension and heart failure.

High cholesterol levels

In normal cases, thyroid hormones help the liver to improve its ability to get rid of excess cholesterol in the body, but when levels of thyroid hormones drop, as in cases of an underactive thyroid gland, the liver's ability to perform this function decreases, which may lead to high cholesterol levels.

Other problems 

An underactive thyroid may also affect the circulatory system in other ways, causing additional problems, such as:

Decreased levels of blood vessel elasticity.
changes in blood pressure;

3. Problems with hair, skin, and nails 

One of the symptoms of an underactive thyroid gland is that it may lead to the emergence of many problems in the hair, skin, and nails as well, such as the following:

Nail problems, such as weak nails and easy breakage.
Skin problems, such as dryness and roughness of the skin, thickening of the skin or thinning and flaking of the skin, and pallor of the skin.
Hair problems, such as alopecia, dry hair, hair thinning, and hair loss from different areas such as the scalp, eyebrows, and legs.

Thyroid hormones are important hormones for the health of hair follicles, and may also contribute to the health of the skin and nails, so low levels may reflect negatively on hair, skin, and nails. It should be noted that many of these symptoms tend to disappear with the start of the patient receiving the necessary treatment.

4. Problems with muscles and joints

An underactive thyroid gland may trigger some joint and muscle problems, such as: 

Pain in the muscles or joints.
Muscle or joint stiffness.
