The most common cause of patients suffering from methanol poisoning is mainly misuse of fake wine or poisoning caused by industrial alcohol. Symptoms of acute poisoning occur after about 18 to 24 hours of incubation of methanol after entering the body.

The symptoms of acute methanol poisoning have three main characteristics: central nervous system inhibition, severe metabolic acidosis, and optic nerve changes.

The early clinical symptoms of methanol poisoning are similar to those of ethanol poisoning, including rapid heartbeat, abdominal pain, vomiting and diarrhea, loss of appetite, headache, dizziness, weakness, gait instability, and deep tendon reflex. Severe patients may cause dizziness or shortness of breath.

More advanced symptoms may include shortness of breath, metabolic acidosis, pancreatitis, hyperglycemia, coma, convulsions, slow heartbeat, left heart failure, shock, elevated white blood cells, rhabdomyolysis, hypokalemia, Acute renal failure, hematuria, slightly higher liver function (fatty degeneration), respiratory failure, retinal damage and optic necrosis.

Methanol damage to the eyes is a major and special manifestation of intoxication and is of great diagnostic value. In addition to the above-mentioned acute symptoms of poisoning, methanol poisoning may also produce permanent neurological sequelae.
