Fatigued woman sweating

Increased sweating. 

Heart and electrocardiogram, heart palpitations


Hand tremor

Trembling hands. 

Intense psychological stress


Woman with tummy ache next to the WC

Increased intestinal transit (without diarrhoea). 

Woman getting out of bed with unrefreshing sleep

Difficulty sleeping. 

Hot hands

Warmer and thinner skin. 

A woman who falls for her hair. Hairfall

Fine, brittle hair. 

Person with muscular weakness in arms and no energy

Muscle weakness in the arms and thighs. 

Buy with a drop of blood and arrows. Menstrual Rhythm Alteration

Altered menstrual rhythm. 

Closed stomach, lack of appetite and anorexia

Mild to moderate weight loss without loss of appetite.  

In the long term, untreated hyperthyroidism increases the occurrence of cardiovascular disease and loss of bone mass.  

Signs of Hyperthyroidism

Clinical signs are a large thyroid and increased heart rate, with hot, clammy, thin skin and trembling hands, as well as increased reflexes. If the cause is Graves' disease, it is important to examine the eyes and assess whether the patient has any eye discomfort (gritty sensation in the eyes, double vision, difficulty or pain when moving the eyes).   

It is also important to know if other family members suffer from thyroid problems or hyperthyroidism.
