Step-by-step explanation:
ONLY: The absence of villi in type 3c can be a problem because villi are small, finger-like projections that line the small intestine and play a crucial role in nutrient absorption. Without villi, the surface area of the small intestine is greatly reduced, which can lead to malabsorption of nutrients such as carbohydrates, proteins, and fats. This can result in malnutrition, weight loss, and other health complications.
Type 3c refers to a subtype of diabetes known as pancreatogenic diabetes, which is caused by damage to the pancreas. In this type of diabetes, the pancreas is unable to produce enough insulin due to damage to the pancreatic tissue. This damage can be caused by a variety of factors, including chronic pancreatitis, pancreatic cancer, or surgery to remove part or all of the pancreas.
