Final answer:
Complications of gestational diabetes, if not well-controlled, include increased risks for coronary artery disease, stroke, vision loss, chronic kidney disease, and diabetic neuropathy.
Step-by-step explanation:
A complication of gestational diabetes is the potential development of long-term consequences similar to those found in other forms of diabetes if the gestational diabetes is not well-controlled. These complications can arise from damage to small blood vessels and include an increased risk of coronary artery disease and stroke. Additionally, there can be damage to blood vessels in the retina leading to vision loss, damage to the kidneys resulting in chronic kidney disease, and diabetic neuropathy due to nerve damage. The risk of such complications is why it's pivotal to carefully monitor and control blood glucose levels during and after pregnancy.
