If you are feeling unwell right now and think your blood sugar may be low

Check your blood sugar if you can. If it's below 70 mg/dL, or you don't have a way to check and you're having symptoms, treat it right away with 15–20g of fast-acting carbohydrate (glucose tablets, juice, or regular — not diet — soda). Recheck in 15 minutes. If symptoms are severe, you're unable to swallow safely, or you don't improve, get emergency medical help immediately. This page is educational information, not emergency guidance for your specific situation.

Common warning signs of low blood sugar

Signs vary person to person, and can develop quickly. Knowing your own early signs matters more than memorizing a general list.

Shakiness, trembling, or feeling suddenly weak

Sweating, especially if it feels sudden and unrelated to heat or activity

Confusion, difficulty concentrating, or feeling "fuzzy"

Rapid heartbeat or a pounding pulse

Sudden irritability, anxiety, or mood change

Dizziness, blurred vision, or extreme hunger

Not everyone with Type 2 diabetes is equally at risk

Higher risk

People on insulin or sulfonylureas (like glimepiride or glipizide) — these medications can cause blood sugar to drop too low, especially if a meal is delayed or skipped.

Lower risk

People managing diabetes through lifestyle alone, or on medications like metformin alone, rarely experience true hypoglycemia from medication — but it's still worth knowing the signs.

If you don't know which category you're in, ask your doctor directly — it changes how cautious you need to be around meal timing, exercise, and alcohol.

Frequently asked questions

What counts as a "low" number?

Generally below 70 mg/dL, but your doctor may give you a different personal target — ask them directly what number should prompt action for you.

Can lifestyle changes alone cause low blood sugar?

It's uncommon without insulin or certain medications, but skipping meals for long periods while on any glucose-lowering medication can still contribute — this is covered in the course's meal-timing guidance.

Is this covered inside the course?

Yes — medication safety and recognizing lows is covered as part of the structured plan, not left for you to piece together separately.

Build a plan that accounts for your actual medication, not a generic one.
