A Bit of Life Clinic

Nutrition therapy for underweight

Structured nutritional rebuilding for patients who are underweight due to poor appetite, malabsorption or digestive illness.

Overview

Being underweight, or losing weight without trying, deserves the same careful attention as weight gain. It can result from poor appetite, a digestive condition affecting absorption, an underlying metabolic or thyroid issue, or the after-effects of illness. Nutrition therapy focuses first on understanding the cause, then rebuilding nutritional status safely.

Common signs and symptoms

  • Unintentional weight loss or difficulty maintaining weight
  • Reduced appetite over weeks or months
  • Fatigue, muscle loss or low energy
  • Digestive symptoms alongside weight changes

What to expect at A Bit of Life Clinic

We investigate for underlying digestive, metabolic or other medical causes with a thorough history, examination and appropriate testing or endoscopy where indicated. Once the cause is understood, we build a structured, staged nutrition plan — covering calorie and nutrient targets, food choices that are easier to tolerate, and where needed, supplementation. Progress is monitored with regular follow-up so the plan can be adjusted as you improve.
