Excess Sweating და Of the heart Waving When Should Check it out. shield-like Gland?
Frequent sweating, a racing heart, or a fluttering sensation do not always mean that the thyroid is the cause, although these symptoms may accompany an overactive thyroid gland (hyperthyroidism). Thyroid hormones affect metabolism, body temperature regulation, and heart rhythm.

Hyperthyroidism (shield-like gland Hyperfunction)
It is a condition where the thyroid gland produces more hormones than the body needs.
The thyroid gland is a small, butterfly-shaped endocrine organ located in the front of the neck. The hormones it produces regulate the body's energy use and metabolism, thus affecting the functioning of almost every organ and system, including the heart rate.
When thyroid hormone levels are elevated, many processes in the body speed up, which can manifest as symptoms such as heart palpitations, excessive sweating, weight loss, tremors, nervousness, and heat intolerance.
How does hyperthyroidism affect the body?
Thyroid hormones (T3 and T4) regulate the activity of processes in the body - metabolism, body temperature, energy production, and heart function. When these hormones are produced in excess by the gland (hyperthyroidism), almost every organ begins to function more intensively.
Why is my heart beating fast?
In hyperthyroidism, the heart responds more strongly to the catecholamines adrenaline and norepinephrine secreted by the adrenal medulla. Hyperthyroidism is also characterized by an increase in circulating blood volume. Ultimately, these processes lead to faster and stronger contractions of the heart muscle, which is often accompanied by palpitations, increased heart rate, and other accompanying sensations.
Why does sweating increase?
Thyroid hormones speed up metabolism, causing the body to produce more energy and therefore more heat.
People with hyperthyroidism often have:
- Excessive sweating
- Constant feeling of heat
- Reduced resistance to high ambient temperatures
Physiologically, when excess heat is produced in the body, one of the main mechanisms for cooling it is the production of sweat and its evaporation. In thyrotoxicosis, due to the acceleration of metabolism, the body produces more heat, in response to which the sweat glands are activated and sweat production increases, which helps maintain normal body temperature.
The simultaneous presence of these two symptoms - palpitations and excessive sweating - especially if they are accompanied by weight loss, hand tremors, anxiety, or insomnia, may be a sign of hyperthyroidism and requires laboratory evaluation of thyroid function (TSH, free T4, and if necessary, free T3).
When Is რეკომენდებული Conducting research?
Thyroid function testing is recommended if you have:
Of the heart Symptoms
- Heart palpitations or rapid pulse even at rest
- Heart rhythm changes
- Sudden anxiety-like episodes accompanied by a racing heart
Sweating და Body Temperature change
- Unusually increased sweating
- Increased sensitivity to high environmental temperatures
Weight და Energy changes
- Unexplained weight loss
- Constant fatigue or weakness
- Severe loss of energy and easy exhaustion
- Hand tremors
- Insomnia and anxiety disorder
- Frequent defecation and more
In addition to the most typical symptoms, hyperthyroidism (toxic goiter) may also cause less characteristic, but noticeable, signs:
- Redness of the palms
- Brittle nails
- Hives-like rash on the skin
- Eye problems such as redness, dryness, or blurred vision (especially in Graves' disease)
- Changes in the menstrual cycle
which one Analyses should be conducted.?
The first stage of research is often:
TSH (thyroid stimulating hormone) is the main screening indicator for assessing thyroid function. Based on the indicator, we can judge whether thyroid function is elevated, normal, or decreased.
If necessary, the doctor may prescribe:
- Free T4 (free thyroxine)
- Free T3 (free triiodothyronine)
- anti-TPO and anti-Tg antibodies — for the evaluation of autoimmune thyroid diseases
- TSH receptor antibodies (TRAb) — especially when Graves' disease is suspected
it's important Know
Heart palpitations and sweating can have many causes — stress, excessive caffeine intake, changes in the sinus node or myocardium, hormonal changes, medications, and other conditions. Therefore, it is not possible to make a diagnostics based on symptoms alone — a doctor's evaluation and appropriate tests are required.
Special attention is needed.
- When planning pregnancy in women with hyperthyroidism
- Having a family history of thyroid disease
- In the presence of a history of heart rhythm disorders
Signs of hyperthyroidism don't always start with just a pounding heart and sweating — sometimes the first changes are fatigue, sleep disturbances, mood swings, or unexplained weight loss. If symptoms are present, simple blood tests can assess thyroid function.
