Worried about husband. he is 29, over weight, sleep apnea, smokes, eats junk food all the time. he just said he feels funny and nauseous.heart attack?

Eating poorly: Those two symptoms could mean a variety of things. I would encourage he visits a doctor and adopt a healthier lifestyle .

See: an internist for evaluation, risk assessment and plan of care. May need smoke cessation plan, weight management and sleep apnea management

See doctor soon: Your husband needs a serious discussion before his health deteriorates rapidly! With better health habits, he will feel better and live longer. Stress to him that he needs to do this for himself and for his family.
