Alcoholism is a chronic illness characterized by habitual excessive alcohol intake that interferes with physical and mental health. It progresses through four stages - from adaptive drinking to loss of control and dependence, with attempts to stop drinking causing severe withdrawal symptoms. Long-term effects include liver disease, cirrhosis, cancer, and neurological damage. Treatment options include medication-assisted therapy combining prescription drugs and counseling, psycho-social therapy through talk therapy, intensive in-patient programs isolating patients for 28 days, and intensive out-patient programs allowing patients to receive treatment while with family.
