The Metabolic and Bariatric Surgery Unit looks into non-communicable diseases, among them diabetes mellitus Type 2, hypertension, obstructive sleep apnoea and dyslipidaemia.
Unit head Professor Zach Koto said: “There are mainly two types of procedures; the restrictive procedure where one restricts the amount of eating, and malabsorptive procedure, which focuses on decreasing the surface of the area where food can be absorbed.”
Koto said they had conducted a restrictive procedure on a patient where they reduced the size of the stomach by two-thirds (70%). “This works by two mechanisms; it reduces the size of the stomach so that the patient eats less.
Secondly, it reduces the hunger hormones where the patient does not feel hungry.
