How is protein calorie malnutrition treated?

Milk-based formulas are the treatment of choice. At the beginning of dietary treatment, patients should be fed ad libitum. After 1 week, intake rates should approach 175 kcal/kg and 4 g/kg of protein for children and 60 kcal/kg and 2 g/kg of protein for adults. A daily multivitamin should also be added.

How do you check for malnutrition?

Diagnosing malnutrition
  1. body mass index (BMI) – a measure that can be used to determine if you're a healthy weight for your height.
  2. whether you've unintentionally lost weight in recent months.
  3. whether an illness means you're unable to feed yourself or absorb nutrients from your diet.

Why malnourished people have bloated stomachs?

Low protein intake and hypoalbuminemia
The extreme lack of protein causes an osmotic imbalance in the gastro-intestinal system causing swelling of the gut diagnosed as an edema or retention of water. Compromised fluid recovery results in the characteristic belly distension observed in highly malnourished children.

How do you evaluate malnutrition?

Historically, serum proteins — albumin, prealbumin (PAB), transferrin, and retinol-binding protein (RBP) — were used to measure malnutrition. C-reactive protein (CRP), total lymphocyte count (TLC), and serum total cholesterol are not serum proteins but sometimes are used as indicators of malnutrition.

What is protein made of?

Proteins are made up of smaller building blocks called amino acids, joined together in chains. There are 20 different amino acids. Some proteins are just a few amino acids long, while others are made up of several thousands. These chains of amino acids fold up in complex ways, giving each protein a unique 3D shape.
