Hand tremors can be a sign of alcoholism, according to MedicineNet. More specifically, tremors or shaky hands are a symptom of alcohol withdrawal, when a person who is dependent on alcohol stops drinking, says WebMD.
Alcoholism is a disease characterized by an inability to control alcohol consumption, states Mayo Clinic. Symptoms of alcohol abuse include blackouts, memory loss, mood swings and nausea associated with drinking alcohol, states WebMD. Risk factors for alcoholism include steady drinking over time, age, family history and depression or other mental illness, claims Mayo Clinic. Alcoholism may also lead to an increased likelihood of motor vehicle accidents or other types of accidents.
