What is type 2 diabetes?
In short The body doesn’t use insulin well and may not make enough. Sugar builds up in the blood, affecting energy, nerves, eyes, kidneys, heart, and circulation over time. The goal is steady control that fits your life and other conditions.
Why it matters: Good daily habits plus the right medicines lower complications, improve energy, and reduce hospital visits.
Urgent concerns (when to act)
- Very high sugars with vomiting, deep breathing, abdominal pain, or confusion
- Severe thirst with very low urine; fever or signs of infection
- Repeated low sugar episodes (shakiness, sweating, confusion) that don’t improve with fast sugar
- Chest pain, shortness of breath, sudden weakness or speech trouble
These can be emergencies — seek urgent medical care.
Common symptoms
- More thirst and urination, especially at night
- Fatigue, blurry vision, slower wound healing
- Tingling or numbness in feet/hands
- Frequent infections (skin, urine, gums)
Often silent
Many people have no obvious symptoms. Regular checks (A1C, kidney, eyes, feet) help catch problems early.
Key tests & follow-up
| Check | Why it matters | Typical frequency |
|---|---|---|
| A1C | Average blood sugar over ~3 months | Every 3–6 months (per plan) |
| Kidney tests (eGFR, urine albumin) | Detect early kidney changes | Yearly or per plan |
| Lipids | Heart risk assessment | Yearly or per plan |
| Eyes (dilated exam) | Find treatable changes early | Yearly (or as advised) |
| Feet (monofilament, pulses) | Prevent sores and infections | At each visit; self-checks weekly |
Targets are individualized based on age, other conditions, and risks. Your clinician sets your plan.
Daily care: plate method & movement
Simple plate method
- Half plate: non-starchy vegetables (greens, cucumber, carrots)
- Quarter plate: protein (fish, chicken, tofu, dal/beans)
- Quarter plate: whole-grain or starchy food (roti, brown rice, small potato)
- Add healthy fats (nuts, olive/mustard oil in moderation)
Smart drink choices
- Water, unsweetened tea/coffee; limit sweet drinks and juices
- Spread fluids through the day; taper in the evening if night urination is an issue
Movement plan
- Short walks after meals (5–10 minutes) help post-meal sugar
- Gentle strength twice weekly (sit-to-stand, light bands)
- Footwear with good support; check feet after walks
Avoiding hypoglycemia
Know the signs
- Shaky, sweaty, fast heartbeat, headache, sudden hunger
- Irritability or confusion; in severe cases, fainting
Quick action plan
- Have fast sugar ready (glucose tabs/gel or sweet drink per plan)
- Recheck after treatment; eat a small snack if the next meal is far away
- Review triggers (missed meal, extra activity, too much medicine)
Medicines overview
Metformin
- Often first choice; helps the body use insulin better
- Common stomach side effects improve when taken with food; kidney function is monitored
SGLT2 inhibitors
- Lower sugar by helping the kidneys pass glucose
- Heart and kidney benefits in many; watch for dehydration, genital infections
GLP-1 receptor medicines
- Help appetite, slow stomach emptying, and improve insulin response
- Often aid weight and heart risk; stomach upset is common early on
Others
- DPP-4 inhibitors; pioglitazone (fluid retention risk); sulfonylureas (low sugar risk); insulin when needed
Choice depends on your goals, kidneys/heart, weight, and cost. Never change doses without guidance.
Sick-day rules
- Check sugars more often during illness
- Keep oral rehydration or low-sugar electrolyte drinks on hand
- Have easy foods (soup, yogurt, khichdi/porridge) if appetite is low
Foot, eye, and kidney checks
Feet
- Daily quick look: between toes, heels, nails
- Socks without tight bands; well-fitting shoes
- Report sores, redness, or numb spots
Eyes & kidneys
- Dilated eye exam yearly helps prevent vision loss
- Kidney tests (eGFR, urine albumin) guide protective treatment
When to call your clinician
- Frequent lows, or sugars staying very high despite your plan
- New foot sore, infection, or swelling
- Vision changes, vomiting/diarrhea > 6–8 hours, or unable to keep fluids down
- Before starting new medicines or supplements that might affect sugar
Quick answers
Do I need to avoid all carbs?
No. Choose portion-controlled whole grains and plenty of non-starchy vegetables. Pair carbs with protein and healthy fats.
Is walking enough?
Post-meal walks help a lot. Add light strength and balance work for joint and fall protection.
Can I fast?
Discuss first. Fasting can change medicine needs and raise low-sugar risk, especially with insulin or sulfonylureas.
What’s a good A1C?
Targets are personalized for seniors based on health and risks. Your clinician will set a safe goal for you.
