This sounds most consistent with lactose intolerance, especially if symptoms recur after milk or dairy. It is uncomfortable but usually manageable, and it is not the same as a milk allergy. I would also consider other causes if fatigue or anxiety persists even without dairy.
Next Steps
Avoid milk for 2â3 weeks and choose lactose-free milk or curd if tolerated; accidental intake is usually managed by stopping the trigger and observing symptoms. If pain, vomiting, breathing difficulty, rash, blood in stool, or persistent weight loss occurs, seek care promptly. Book a Practo consultation or visit me at Synergy Multispeciality Hospital, Miraj for assessment.
