You must regularly visit an eye doctor, such an optometrist or ophthalmologist, to check for these potentially serious conditions. According to guidelines from the American Diabetes Association, people with type 1 diabetes should have an annual dilated comprehensive eye exam beginning five years after diagnosis. People with type 2 diabetes should have this comprehensive dilated eye exam yearly beginning at diagnosis.
Rosiglitazone, a thiazolidinedione, has not been found to improve long-term outcomes even though it improves blood sugar levels. Additionally it is associated with increased rates of heart disease and death. Angiotensin-converting enzyme inhibitors (ACEIs) prevent kidney disease and improve outcomes in those with diabetes. The similar medications angiotensin receptor blockers (ARBs) do not. A 2016 review recommended treating to a systolic blood pressure of 140 to 150 mmHg.
Amino acid metabolism may play a key role early in the development of type 2 diabetes. Wang et al reported that the risk of future diabetes was at least 4-fold higher in normoglycemic individuals with high fasting plasma concentrations of 3 amino acids (isoleucine, phenylalanine, and tyrosine). Concentrations of these amino acids were elevated up to 12 years prior to the onset of diabetes.  In this study, amino acids, amines, and other polar metabolites were profiled using liquid chromatography tandem mass spectrometry.
Accumulating evidence suggests that depression is a significant risk factor for developing type 2 diabetes. Pan et al found that the relative risk was 1.17 in women with depressed mood and 1.25 in women using antidepressants.  Antidepressant use may be a marker of more severe, chronic, or recurrent depression, or antidepressant use itself may increase diabetes risk, possibly by altering glucose homeostasis or promoting weight gain.
Another diabetes-related sexual dysfunction symptom in men is reduced amounts of ejaculation, or retrograde ejaculation. Retrograde ejaculation is a condition in which the semen goes into the bladder, rather than out of the body through the urethra. Diabetes and damage to the blood vessels causes nerve damage to the muscles that control the bladder and urethra, which results in this problem.
Gestational diabetes can be a scary diagnosis, but like other forms of diabetes, it’s one that you can manage. It doesn’t mean that you had diabetes before you conceived or that you will have diabetes after you give birth. It means that, by working with your doctor, you can have a healthy pregnancy and a healthy baby. No matter what, know that you have all the support you need for both you and your baby to be at your best.
It is a good idea to wear a MedicAlert bracelet or tag that says you have diabetes. This will make others aware of your condition in case you have a severe hypoglycemic attack and are not able to make yourself understood, or if you are in an accident and need emergency medical care. Identifying yourself as having diabetes is important because hypoglycemic attacks can be mistaken for drunkenness, and victims often aren't able to care for themselves. Without prompt treatment, hypoglycemia can result in a coma or seizures. And, because your body is under increased stress when you are ill or injured, your blood sugar levels will need to be checked by the medical personnel who give you emergency care.
Culturally appropriate education may help people with type 2 diabetes control their blood sugar levels, for up to 24 months. If changes in lifestyle in those with mild diabetes has not resulted in improved blood sugars within six weeks, medications should then be considered. There is not enough evidence to determine if lifestyle interventions affect mortality in those who already have DM2.
When it comes to prediabetes, there are no clear symptoms—so you may have it and not know it. Here’s why that’s important: before people develop type 2 diabetes, they almost always have prediabetes—blood sugar levels that are higher than normal but not yet high enough to be diagnosed as diabetes. You may have some of the symptoms of diabetes or even some of the complications.
Type 2 diabetes is characterized by a combination of peripheral insulin resistance and inadequate insulin secretion by pancreatic beta cells. Insulin resistance, which has been attributed to elevated levels of free fatty acids and proinflammatory cytokines in plasma, leads to decreased glucose transport into muscle cells, elevated hepatic glucose production, and increased breakdown of fat.

It would be advisable to see a doctor for further evaluation, if you experience one of these diabetes symptoms in men. Generally, retrograde ejaculation doesn’t need formal treatment unless fertility is a problem. Treatment options may include medications that help keep the bladder neck muscle closed during ejaculation – however these only work if the problem is caused by nerve damage, such as in diabetes.
In both diabetic and nondiabetic patients, coronary vasodilator dysfunction is a strong independent predictor of cardiac mortality. In diabetic patients without coronary artery disease, those with impaired coronary flow reserve have event rates similar to those with prior coronary artery disease, while patients with preserved coronary flow reserve have event rates similar to nondiabetic patients. 
Diabetes is a chronic disease, for which there is no known cure except in very specific situations. Management concentrates on keeping blood sugar levels as close to normal, without causing low blood sugar. This can usually be accomplished with a healthy diet, exercise, weight loss, and use of appropriate medications (insulin in the case of type 1 diabetes; oral medications, as well as possibly insulin, in type 2 diabetes).
Also called diabe·tes mel·li·tus [mel-i-tuh s, muh-lahy-] . a disorder of carbohydrate metabolism, usually occurring in genetically predisposed individuals, characterized by inadequate production or utilization of insulin and resulting in excessive amounts of glucose in the blood and urine, excessive thirst, weight loss, and in some cases progressive destruction of small blood vessels leading to such complications as infections and gangrene of the limbs or blindness.
Type 1 diabetes is characterized by loss of the insulin-producing beta cells of the pancreatic islets, leading to insulin deficiency. This type can be further classified as immune-mediated or idiopathic. The majority of type 1 diabetes is of the immune-mediated nature, in which a T cell-mediated autoimmune attack leads to the loss of beta cells and thus insulin. It causes approximately 10% of diabetes mellitus cases in North America and Europe. Most affected people are otherwise healthy and of a healthy weight when onset occurs. Sensitivity and responsiveness to insulin are usually normal, especially in the early stages. Although it has been called "juvenile diabetes" due to the frequent onset in children, the majority of individuals living with type 1 diabetes are now adults.
Retinopathy — Tiny blood vessels in the retina (the back of the eye that sees light) can become damaged by high blood sugar. The damage can block blood flow to the retina, and can lead to bleeding into the retina. Both damage the ability of the retina to see light. Caught early, retinopathy damage can be minimized by tightly controlling blood sugar and using laser therapy. Untreated retinopathy can lead to blindness.
Diabetes is a disease that affects your body’s ability to produce or use insulin. Insulin is a hormone. When your body turns the food you eat into energy (also called sugar or glucose), insulin is released to help transport this energy to the cells. Insulin acts as a “key.” Its chemical message tells the cell to open and receive glucose. If you produce little or no insulin, or are insulin resistant, too much sugar remains in your blood. Blood glucose levels are higher than normal for individuals with diabetes. There are two main types of diabetes: Type 1 and Type 2.
The top 10 countries in number of people with diabetes are currently India, China, the United States, Indonesia, Japan, Pakistan, Russia, Brazil, Italy, and Bangladesh. The greatest percentage increase in rates of diabetes will occur in Africa over the next 20 years. Unfortunately, at least 80% of people in Africa with diabetes are undiagnosed, and many in their 30s to 60s will die from diabetes there.
Dietary factors also influence the risk of developing type 2 diabetes. Consumption of sugar-sweetened drinks in excess is associated with an increased risk. The type of fats in the diet are important, with saturated fats and trans fatty acids increasing the risk, and polyunsaturated and monounsaturated fat decreasing the risk. Eating a lot of white rice appears to play a role in increasing risk. A lack of exercise is believed to cause 7% of cases. Persistent organic pollutants may play a role.
