Diabetes medication: simple, useful facts you can use

Choosing a diabetes medicine affects daily life — energy, appetite, and even heart health. This page gives clear, practical info on the main drug types, what they do, and real‑world tips so you can ask better questions at the clinic.

Common drug types and what they do

Metformin. Often the first drug prescribed for type 2 diabetes. It lowers liver glucose production and improves insulin sensitivity. Expect possible stomach upset at first; kidney checks matter because the dose depends on kidney function.

SGLT2 inhibitors (example: dapagliflozin). These drugs make the kidneys flush out extra sugar. They can help with weight loss and cut hospitalizations for heart failure in many trials. Side effects to watch: genital yeast infections, dehydration, and they work less well when kidney function is low. See our Dapasmart article for a focused look at dapagliflozin.

GLP‑1 receptor agonists (examples: semaglutide, exenatide). They boost insulin release when you eat, slow stomach emptying, and often reduce appetite. Many people lose weight on these drugs. Common complaints: nausea and occasional stomach upset. They may be chosen when weight loss or stronger A1c drops are needed.

Insulin. Used in type 1 diabetes and many people with type 2 when other drugs aren’t enough. There are basal (long‑acting) and bolus (short‑acting) types. Insulin gives the most reliable blood‑sugar control but raises hypoglycemia risk, so dose timing and carb counting matter.

Sulfonylureas and meglitinides (examples: glipizide, repaglinide). These increase insulin release but can cause low blood sugar and weight gain. They’re cheap and effective short term, but require careful monitoring.

DPP‑4 inhibitors (example: sitagliptin). They give modest A1c drops and are gentle on the stomach. They’re usually weight‑neutral and have low hypoglycemia risk when used alone.

Practical tips for daily life

Get your A1c target from your clinician — many aim near 7% but goals change with age and other health issues. Check kidney function and liver tests before starting some drugs. Watch for specific side effects: genital infections with SGLT2s, nausea with GLP‑1s, and low blood sugar with insulin or sulfonylureas.

Cost and access matter. If a newer drug works better but costs too much, ask about patient assistance, generics, or alternatives. Combine medicine with small, steady lifestyle changes — 20–30 minutes of walking most days and consistent meals help medications work better.
