This document provides information on the diagnosis, symptoms, signs, screening, and treatment of diabetes mellitus. It defines the main types of diabetes as type 1, type 2, gestational diabetes, and prediabetes conditions. It outlines the diagnostic criteria and recommendations for screening asymptomatic individuals. Signs and symptoms of diabetes as well as potential complications are described. Treatment aims and options including lifestyle modifications, oral hypoglycemic agents, and insulin therapy are summarized. The document also discusses prevention and management of diabetes complications focused on cardiovascular, renal, foot, and eye health.

to maintain general health so as to allow the person to live a normal and active live. *α-glucosidase inhibitors: add to diet or other OHGA therapy to improve glucose control, or
avoidance of acute hyper/hypoglycaemic complications and chronic vascular complications. as a monotherapy
A) Lifestyle modification – first line Rx for type 2 diabetics. Attempt for 2-4 mths C) Insulin Therapy
Medical Nutrition Therapy Low saturated fat & cholesterol Indications
Low sodium for individuals with HPT Type 1 diabetics
Physical Activity & Exercise Recommendation: 3-5X / wk, 60-85% max heart rate, 20- Failure of lifestyle modification and OHGA in glycaemic control in type 2 diabetics
60min each time. Aerobic exercise recommended. During acute illness or stress for glycaemic control in type 2 diabetics
Precautions
- Proper footwear Regimen (short acting = Actrapid, long-acting = Insulatard)
- Adequate hydration Multiple daily injections (regular insulin before each meal + intermediate or long acting
- Avoid heavy resistance & isometric exercise insulin as basal insulin)
- Avoid exercise when severly hyperglycaemic or 2 injections per day (mixture of regular & intermediate-acting insulin before breakfast and
hypoglycaemic for Type 1 diabetics dinner – 2/3 of total daily dose in the morning in ratio of 1:2 of short:intermediate acting
Prevention of hypoglycaemia insulin; 1/3 of total daily dose in the evening)
- Reduce medication prior to exercise Single injection of intermediate acting insulin at bedtime + OHGA during the day (for Type
- Consume some CHO 30-60 min before exercise and 2 diabetics only)
after 30 mins of exercise Alternatives: Rapid-acting insulin analogues (eg lispro) – not recommended as for now.
- Gradual progression of exercise intensity
- Avoid late night exercise Type 1 Diabetics: Multiple daily injection or Continuous subcutaneous insulin infusion (CSII)
Smoking cessation Type 2 Diabetics: stepwise therapy with multiple pharmacological therapies needed over
Alcohol Alcohol consumption discouraged time to maintain target glucose control. 2 or more OHGA, or insulin Rx ± OHGA may be
required

4. Prevention of Renal Complications Diabetic Foot Complications
Main risks: ulcers & LL amputations
Diabetic nephropathy (DN) accounts for 40% of PTs starting renal dialysis in S’pore Major cause of disability & mortality
Type 1 DM usually presents with Microalbuminuria 5-15 yrs after onset Screening: at dx & annually.
Type 2 DM usually presents already with overt proteinuria Wagner’s Classification:
Rate of decline in GFR = 2-20ml/min/year. a. At risk for lower extremity amputation
Screening for Microalbuminuria b. Not at risk for lower extremity amputation
Dipstix test Risk factors for lower limb amputation
Type 1: annually after 5YO Previous Hx of prev. ulceration

Stage II: microalbuminemia (>30 mg/d)
Stage III: preoteinuria (>300mg/d)—irreversible from here onwards Not at risk Primary med practitioner & Screening of foot
Stage IV: renal impairment (Cr >200) diabetic foot care nurse DM footcare education
Stage V: ESRF (Cr >900)—start preparing for dialysis when Cr ~>500 At risk Specialist footcare team Wound debridement
Pressure analysis
Management: Orthoses / insoles for pressure distribution
Glycaemic control Aim for HbA1c <7% Footwear adaptations
BP control Aim for <130/80mmHg DM footcare education
For those with over nephropathy w proteinuria >1g/day, aim for
<125/75mmHg
st
ACE-I is preferred 1 line drug as it reduces proteinuria and slows
rate of decline of GFR. Check electrolytes 7days after introduction,
and monitor for ↑K+ or ↓ing GFR
Low Protein diet Delay progression of CRF in type 1 diabetics with overt nephropathy
Lipid control Reduce proteinuria and rate of decline in GFR in DN
Smoking Risk factor in devt of DN
