๐งฌType 1 vs Type 2: in Type 1 the pancreas makes no insulin โ you dose all of it. In Type 2 the body resists insulin; pills and weekly shots help it work better. That's why the med shelf changes with your pick.
๐CGM = continuous glucose monitor โ a small sensor on your arm that reads glucose around the clock. The graph up top is what its app shows you.
๐ฏTime in Range (TIR) = % of time between 70โ180 mg/dL โ the number your care team watches. Goal: 70%+.
๐ฉธBody Health tracks blood-sugar damage. Time high slowly harms eyes, nerves, kidneys; lows hurt fast. Stay in range and it recovers.
โค๏ธHeart Health tracks cholesterol/cardiac risk. Fatty, fried, and junk food plus alcohol erode it; veggies, fish, nuts and exercise rebuild it. A bacon plate is easy on your sugar but hard on your heart.

Pro moves reward pre-bolusing โ insulin before you eat so it's working when carbs hit. Insulin takes ~20โ30 min to kick in, so timing matters.
๐ฌThe 15-15 rule for lows: eat 15g of fast sugar (glucose tabs, juice), wait 15 minutes, recheck. Repeat if still under 70. Don't panic-eat the whole kitchen โ that causes a rebound high.
๐บAlcohol is sneaky: it can cause a delayed low hours later โ even overnight โ because the liver gets busy clearing alcohol and stops releasing backup sugar. Sweet drinks spike first, then drop.
๐Rapid insulin acts fast, corrects highs โ but lags ~20โ30 min, and stacking doses causes lows. Basal (long-acting) insulin is steady background coverage, taken once daily.
๐Pills differ: Metformin & SGLT2 rarely cause lows; a Sulfonylurea squeezes the pancreas and can; GLP-1 (a weekly shot) slows digestion and curbs appetite (helps weight & heart).
๐Fat delays the spike: greasy meals (pizza, fries) digest slowly, so glucose rises later and longer โ the classic "why am I high hours after eating?" effect. Watch the graph a few hours after a fatty meal.

Dawn phenomenon: in the early morning (~3โ7am) your body releases wake-up hormones that nudge glucose up โ many people run higher at breakfast for no "reason." It's normal; it's on the graph.
