The three main types of hand tremors are tremors that occur when the hand is resting; a tremor that appears only when moving the hand (called a kinetic tremor) and stops when the hand is resting; and a postural tremor that occurs when the hand is held in a certain position for a period of time. Hand tremors may be caused by a medical condition and should thus be evaluated by a physician.
Parkinson's Disease is a chronic condition that worsens over time. Parkinson's results from malfunctioning of cells in the brain that produce a chemical called dopamine. The cells that produce this chemical begin to die, producing less dopamine and affecting a person's ability to move and control movements. Hand tremors are a common symptom of Parkinson's. Other symptoms include tremors that affect the face and legs, stiffness, slow movement and a lack of coordination and balance.
Hypoglycaemia, also known as low blood sugar, can be mild, moderate or severe. Hypoglycaemia is common in people who have diabetes but can occur in non-diabetics as well. Hand tremors are one of the first symptoms experienced in mild hypoglycaemia along with hunger, nausea, rapid heartbeat, nervousness, cold, clammy skin and sweating. If you experience any of these symptoms, it is important to see a physician as soon as possible.
Strong emotions such as anger, rage, anxiety, fatigue and stress can cause hand tremors. They are usually temporary and will go away when the person is relaxed. Remedies for hand tremors caused by stress or anxiety include meditation, relaxation techniques and breathing exercises. If fatigue is the cause of hand tremors, try getting more sleep.
Hyperthyroidism, also known as an overactive thyroid, is caused by the thyroid gland producing an excess of thyroid hormone. The thyroid glands are located under the Adam's apple in the neck. Hand tremors, excessive sweating, feeling cold, nervousness, weight loss, fatigue and rapid heartbeat are all symptoms of hyperthyroidism.
Multiple sclerosis (MS) is an autoimmune disease that affects the brain and spinal cord. White blood cells attack the myelin sheath, which are the protective coverings for nerve fibres in the brain. The nerve fibres become exposed and are unable to transmit nerve impulses effectively. Scar tissue called sclerosis builds up due to the destruction of the myelin sheath. Hand tremors are common in people with MS. Tremors can be intermittent, meaning they come and go. The two types of hand tremors in MS are an intention tremor and a postural tremor. An intention tremor will occur when reaching for something. A postural tremor occurs when holding the hand in a certain position.
