What is Collagen?
Collagen is the most abundant protein in the human body and forms the basic structure of skin, bones, cartilage, tendons, and connective tissue. Collagen production decreases with age.
Collagen and Weight Loss
After a bariatric operation and significant weight loss, the skin can become slack. Collagen plays an important role in skin elasticity and firming.
Types of Collagen
- Type I: Skin, bones, tendons (most common type)
- Type II: Cartilage
- Type III: Blood vessels, internal organs
Collagen After Bariatric Surgery
Adequate protein intake (at least 60–80 g/day) supports the body’s own collagen production. Vitamin C is essential for collagen synthesis.
Collagen-Rich Foods

- Fish (especially skin)
