- Active Flare of Inflammatory Bowel Disease (Ulcerative Colitis)
Medical Background
Mr. Rajesh Kumar, a 59-year-old retired school teacher, was referred for nutrition counseling during an active flare of Inflammatory Bowel Disease (Ulcerative Colitis). He complained of frequent diarrhea, abdominal cramps, severe weakness, poor appetite, and painful leg cramps. Over the previous two months, he had lost 4 kg and had become reluctant to eat due to fear of worsening his gastrointestinal symptoms. Persistent diarrhea had resulted in significant electrolyte losses, placing him at risk of dehydration and malnutrition.
Key Challenges
- Active Ulcerative Colitis flare-up
- Severe hypokalemia due to persistent diarrhea
- Dehydration and electrolyte imbalance
- Poor appetite and reduced oral intake
- Weight loss and risk of protein-energy malnutrition
- Muscle cramps and weakness affecting daily activities
He was referred to Dytoclick for structured nutrition counseling and therapeutic dietary management during the acute flare.

Dietary Objectives
Correct hypokalemia and electrolyte imbalance
Increase intake of potassium-rich foods and oral rehydration to restore electrolyte balance and resolve muscle cramps.
Reduce diarrhea and support gut healing
Adopt a low-residue, soft diet to minimize bowel irritation and reduce stool frequency during the active flare.
Prevent malnutrition and weight loss
Ensure adequate calorie and protein intake through small, frequent, easy-to-digest meals to reverse weight loss and prevent protein-energy malnutrition.
Improve appetite and oral intake
Introduce practical, appealing, and well-tolerated food options to overcome fear of eating and rebuild dietary confidence.
Nutrition Intervention
Low-Residue, Electrolyte-Focused Nutrition Plan
Designed a 1,900–2,100 kcal/day low-residue, soft diet with potassium-rich foods such as banana, coconut water, potato, pumpkin, and papaya to correct hypokalemia.
Small, Frequent Meal Structuring
Recommended small, frequent meals every 2–3 hours using soft, easy-to-digest foods including khichdi, rice porridge, curd, and soups to improve tolerance and intake.
Protein and Supplement Support
Ensured adequate protein intake through eggs, fish, paneer, and tofu, and added oral nutrition supplements when dietary intake was insufficient.
