Tingling hands may be caused by a variety of conditions or diseases. According to the MedlinePlus website, tingling in the hands usually indicates an underlying nerve-related condition. Tingling sensations may occur in one or both hands, depending on the cause. In some cases, tingling is accompanied by other sensations, such as numbness or burning. A person with tingling in the hands should visit her doctor for an evaluation.
Alcoholic Neuropathy
Alcoholic neuropathy, a direct result of alcoholism, causes tingling in the hands. According to the University of Maryland Medical Center, or UMMC, alcoholic neuropathy involves alcohol-related nerve damage. The extremities -- including the hands, fingers, feet and toes -- are common locations for nerve damage in alcoholics. Although the exact cause of alcohol-related nerve damage is unknown, the condition may be caused by alcohol's toxicity on the nerves or the poor nutrition that often accompanies alcoholism. Common signs and symptoms associated with alcohol-related nerve damage include pain, numbness and tingling in the extremities; muscle weakness; cramps and aches; urinary incontinence or leaking urine; the sensation of incomplete bladder evacuation; constipation or diarrhea; and nausea and vomiting. The UMMC states that treating the underlying alcohol problem is an essential part of the overall treatment plan for alcoholic neuropathy.
Carpal Tunnel Syndrome
Carpal tunnel syndrome is a common cause of bilateral hand tingling or simultaneous tingling in both hands. The National Institute of Neurological Disorders and Stroke, or NINDS, states that carpal tunnel syndrome occurs when the median nerve is compressed as it travels through the carpal tunnel at the wrist. The median nerve supplies sensation and motor control to various hand structures. The carpal tunnel is a narrow passageway in the wrist, bound by carpal bones and a fibrous band called the flexor retinaculum. Anything that compresses the median nerve in the wrist can cause carpal tunnel syndrome symptoms. Common signs and symptoms associated with carpal tunnel syndrome include burning, tingling, itching or numbness in the fingers and the palm of the hand; swollen fingers; reduced grip strength; and wasting of the hand muscles. According to the NINDS, workstation modifications along with postural exercises may help prevent carpal tunnel syndrome.
Diabetes
Tingling of the hands is a common and serious complication associated with diabetes. Diabetic neuropathy is a type of nerve damage that may occur in diabetics. Elevated blood sugar levels can injure nerves throughout the body, although the nerves in the extremities are most commonly affected. According to MayoClinic.com, common signs and symptoms associated with diabetes neuropathy include tingling, burning or numbness in the hands and feet; sharp pain in the affected area that is often worse at night; extreme sensitivity to light touch; decreased muscle strength; and joint pain. Diabetes-related nerve damage occurs following prolonged exposure to elevated blood sugar, although other factors may contribute to this problem. These factors include nerve inflammation caused by autoimmune conditions, genetic components and tobacco consumption. MayoClinic.com states that diabetic neuropathy may be prevented by controlling blood sugar levels.
