Microvascular complications are degenerative changes occurring in the small vessels such as:

Choice A reason: Breastfed babies typically have unformed (rather than formed) stools that are yellow and seedy, not yellowish-brown. Formula-fed babies tend to have more formed stools that are light brown or tan in color. The stooling frequency is often higher in breastfed babies compared to formula-fed babies.

Choice B reason: This description is incorrect. Formula-fed babies typically have more formed stools that can range from light brown to tan, rather than yellow. Breastfed babies usually have yellow, unformed stools and tend to stool more frequently.

Choice C reason: Breastfed babies have soft, unformed, and yellow stools due to the easy digestibility of breast milk. Formula-fed babies tend to have less frequent stooling patterns and their stools are more formed and light brown in color. This difference is due to the different compositions of breast milk and formula.

Choice D reason: Breastfed babies do not usually have light brown stools; their stools are typically yellow and unformed. Formula-fed babies can have yellow stools in some cases, but more commonly, their stools are light brown or tan and more formed.

Choice A reason: Neuropathies occur due to the thickening, sclerosis, obstruction, and ischemia of the small blood vessels that supply the nerves (vasa nervorum). Chronic hyperglycemia leads to damage of these blood vessels, reducing blood flow and oxygen supply to the nerves. This ischemia results in nerve degeneration, delayed nerve conduction, and impaired sensory function, which are characteristic of diabetic neuropathy.

Choice B reason: Infection in the nerves is not a primary cause of diabetic neuropathy. While infections can affect the nerves, the neuropathy associated with diabetes is primarily due to vascular complications and chronic hyperglycemia, not infections.

Choice C reason: Excessive glucose exposure to the brain and spinal cord is not directly related to neuropathy. The neuropathic complications in diabetes are due to the damage of peripheral nerves caused by hyperglycemia and vascular insufficiency, rather than glucose affecting the central nervous system.

Choice D reason: Inability to provide continuous glucose to the brain and spinal cord is not a cause of neuropathy. The brain and spinal cord typically have a continuous supply of glucose. Neuropathy in diabetes results from the damage to the peripheral nerves due to prolonged high blood glucose levels and subsequent vascular complications.
