Hello and welcome to Healthcare Magic. Thanks for your query.
I appreciate your concern for your brother. I think it would be definitely advisable to consult a doctor. The reasons are 1) for the acute effects due to the excessive drinking such as alcoholic gastritis
, etc. 2) for the possible chronic effects of drinking like liver
problems, etc. 3) for help in stopping this habit (de-addiction).
So, please motivate and convince your brother to seek medical help
Wish you all the best.
- Dr. Jonas Sundarakumar
