Hello and welcome to Healthcare Magic. Thanks for your query.
following stopping alcohol abruptly may be a symptom of alcohol withdrawal
Recurrent or persistent cough may be due to a variety of conditions like smoking
, lung infections, etc. A proper examination and a chest xray may be required to determine the cause of his cough.
High levels of triglicerides can be due to obesity, unhealthy dietary habits and also due to excessive alcohol consumption.
Since you appear concerned about your friend's health condition, I would suggest that you take him to a doctor for detailed evaluation and further management. He may also need help in controlling his drinking habit. So, please support and advise him accordingly.
Wish you all the best.
