Original source overview
What is diabetes?Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. The cells of your body need glucose for energy. A hormone called insulin helps the glucose get into your cells.

What are the treatments for diabetes?Treatments for diabetes can depend on the type. Common treatments include a diabetic meal plan, regular physical activity, and medicines. Some less common treatments are weight loss surgery for either type and an artificial pancreas or pancreatic islet transplantation for some people with type 1 diabetes.
Who needs diabetes medicines?People with type 1 diabetes need to take a diabetes medicine called insulin to control their blood sugar.
Some people with type 2 diabetes can control their blood sugar with healthy food choices and physical activity. But for others, a diabetic meal plan and physical activity are not enough. They need to take diabetes medicines.
The kind of medicine you take depends on your type of diabetes, daily schedule, medicine costs, and any other health conditions that you have. Over time, you may need to take more than one diabetes medicine.
What are the types of medicines for type 1 diabetes?If you have type 1 diabetes, you must take insulin because your body no longer makes it. There are different types of insulin that start to work at different speeds, and the effects of each last a different length of time. Your health care provider will measure your blood glucose to decide on the type of insulin. You may need to use more than one type.
You will also need to check your blood sugar at home. Your provider will tell you how often. The results of your blood sugar testing can help you make decisions about food, physical activity, and medicines.
You can take insulin several different ways. The most common are with a needle and syringe, an insulin pen, or an insulin pump. If you use a needle and syringe or a pen, you have to take insulin several times during the day, including with meals. An insulin pump gives you small, steady doses throughout the day. Less common ways to take insulin include inhalers, injection ports, and jet injectors.
In rare cases, taking insulin alone might not be enough to manage your blood sugar. Then you would need to take another diabetes medicine.
What are the types of medicines for type 2 diabetes?There are several different medicines for type 2 diabetes. Each works in a different way. Many of them are pills. There are also medicines that you inject under your skin, such as insulin.
Over time, you may need more than one diabetes medicine to manage your blood sugar. You might add another diabetes medicine or switch to a combination medicine. A combination medicine contains more than one type of diabetes medicine in the same pill. Some people with type 2 diabetes take both pills and injections.
Even if you don't usually take insulin, you may need it at special times, such as during pregnancy or if you are in the hospital.
What else should I know about taking medicines for diabetes?Even if you take medicines for diabetes, you still need to eat a healthy diet, stop smoking, take your other medicines, and get regular physical activity. These will help you manage your diabetes.
It is important to make sure that you understand your diabetes treatment plan. Talk to your provider about:
• What your target blood sugar level is • What to do if your blood sugar gets too low or too high • Whether your diabetes medicines will affect other medicines you take • If you will have any side effects from the diabetes medicines
You should not change or stop your diabetes medicines on your own. Talk to your provider first.

Encyclopedic background — Wikipedia
The following selected excerpts provide background on “Diabetes medication”. This related background source does not cover every aspect of the specific topic “Diabetes Medicines”; population-specific details and decisions should be checked in the original topic source. They are not a substitute for the source overview or current local clinical guidance. Each excerpt below comes from the fixed Wikipedia revision [W1].
Definition and overview [W1]
Drugs used in diabetes treat types of diabetes mellitus by decreasing glucose levels in the blood. There are different classes of drugs for treating diabetes, and selection of the appropriate agent depends on the nature of the diabetes (Type I vs Type II), the age and situation of the person, as well as other patient factors.
Type 1 diabetes is an endocrine disorder characterized by hyperglycemia due to autoimmune destruction of insulin-secreting pancreatic beta cells. Insulin is a hormone needed by cells to take in glucose from the blood. Insufficient levels of insulin due to Type 1 diabetes can lead to chronic hyperglycemia and eventual multiorgan damage, resulting in renal, neurologic, cardiovascular, and other serious complications. The treatment for Type 1 diabetes involves regular insulin injections.
Type 2 diabetes, the most common type of diabetes, occurs when cells exhibit insulin resistance and become unable to properly utilize insulin. Insulin resistance requires the pancreas to compensate by increasing insulin production. Once compensation fails, chronic hyperglycemia can manifest and type 2 diabetes develops. Treatments include dietary changes emphasizing low glycemic index food, physical activity to improve insulin sensitivity, and medications that (1) increase the amount of insulin secreted by the pancreas, (2) increase the sensitivity of target organs to insulin, (3) decrease the rate at which glucose is absorbed from the gastrointestinal tract, and (4) increase the loss of glucose through urination.
Mechanisms of action [W1]
Insulin sensitization: Increased sensitivity of insulin receptors on cells leading to decreased insulin resistance, and higher effects of insulin on blood glucose levels.
Stimulation of beta cells: This stimulation increases insulin secretion from beta cells of pancreas.
Alpha-glucosidase inhibition: Inhibition of the alpha-glucosidase enzyme, decreases the rate at which glucose is absorbed from the gastrointestinal tract.
Reading this topic in context
Use “Diabetes Medicines” as a starting point for a focused discussion, rather than treating every statement in the broader encyclopedia article as applying to you. The original source overview and the background excerpts answer different questions: the overview explains the health topic for readers, while the encyclopedia supplies terminology and general context. Keep a record of which questions concern symptoms, a confirmed diagnosis, prevention, or an existing treatment. This helps a healthcare professional address the relevant issue without relying on an internet label.
Questions to take to a professional
1. Why is this medicine being selected for my circumstances?
2. What should my plan say about low glucose, illness, missed doses and interactions?
Evidence, scope and next steps
The health-topic overview is attributed to MedlinePlus / the National Library of Medicine at the original topic link below. Wikipedia [W1] is a secondary background source; its references can support further reading, but their presence is not evidence that WellPrimer has independently reviewed every study. No clinical review, guideline certification or NLM endorsement is claimed. For screening intervals, diagnostic thresholds, pregnancy or child-specific advice and treatment choices, check current guidance in your country with a qualified professional. Do not start, stop or change a prescribed medicine based on encyclopedia excerpts. New or worsening symptoms need appropriate clinical assessment rather than more reading alone.
