Patient Education for Diabetes Follow-Up and Precautions

Essential Laboratory Testing to Schedule

You need to schedule follow-up with your provider for specific blood tests to screen for and monitor diabetes and thyroid function. 1, 2

Required Laboratory Tests:

  • Fasting plasma glucose (FPG) - requires 8 hours of no food or drink except water to diagnose diabetes (abnormal if ≥126 mg/dL) 1
  • Hemoglobin A1C (HbA1C) - measures average blood sugar over 2-3 months (diabetes diagnosed if ≥6.5%) 1, 2
  • Thyroid function tests - thyroid problems commonly occur alongside diabetes and affect metabolism 2
  • Lipid panel - checks cholesterol and triglycerides (should be done at diabetes diagnosis and every 5 years if under 40) 3
  • Kidney function tests - essential before starting diabetes medications like metformin 4, 5

Testing Schedule:

  • If tests are normal, repeat screening at least every 3 years 1
  • If you have diabetes, A1C should be checked every 3 months until blood sugar is controlled, then at least twice yearly 1, 4

Critical Diabetes Precautions You Must Follow

Recognize Emergency Warning Signs - Seek Immediate Medical Care If You Experience:

Lactic acidosis is a rare but life-threatening emergency that requires hospital treatment. Stop any diabetes medication and call 911 if you develop: 5

  • Severe weakness or unusual muscle pain
  • Trouble breathing or unusual sleepiness
  • Unexplained nausea, vomiting, or diarrhea
  • Feeling cold in hands/feet or feeling dizzy/lightheaded
  • Slow or irregular heartbeat

Daily Blood Sugar Monitoring Precautions:

Low blood sugar (hypoglycemia) can occur, especially if you skip meals, drink alcohol, or take certain medications. Warning signs include: 1, 5

  • Shakiness, sweating, confusion
  • Rapid heartbeat, hunger, irritability
  • Always carry a fast-acting sugar source (glucose tablets, juice, regular soda) 1
  • Teach family members to recognize these symptoms 1

High blood sugar (hyperglycemia) symptoms include: 5

  • Increased thirst and frequent urination
  • Blurred vision and fatigue
  • Slow-healing wounds

Medication Safety Precautions:

If prescribed metformin (the most common first-line diabetes medication): 4, 5

  • Take with meals to reduce stomach upset 5
  • Stop taking and contact your provider immediately before any surgery, X-rays with contrast dye, or if you become severely ill with vomiting/diarrhea 5
  • Limit alcohol consumption - both binge drinking and regular heavy drinking increase risk of dangerous complications 5
  • Report if you develop persistent diarrhea, nausea, or upset stomach 5

Situations Requiring Immediate Provider Contact:

You have higher risk of complications if you: 5

  • Have kidney or liver problems
  • Become dehydrated from illness, fever, vomiting, or diarrhea
  • Experience severe infection, heart attack, or stroke
  • Need surgery or cannot eat/drink normally
  • Are over 80 years old

Lifestyle Modifications to Prevent Diabetes Complications

Dietary Changes (Start Immediately):

Follow a heart-healthy eating pattern to control blood sugar, blood pressure, and cholesterol: 1, 4

  • Limit fat to ≤30% of daily calories, with <7% from saturated fat 1
  • Restrict sodium to ≤1,500 mg daily 1
  • Eat minimum 3 oz whole grains, 2 cups fruit, and 3 cups vegetables daily 1
  • Limit sweets and sugar-sweetened beverages; when eating sweets, combine with other foods to slow blood sugar rise 1

Exercise Requirements:

Engage in at least 150 minutes per week of moderate-intensity aerobic activity (brisk walking, swimming, cycling) 4

  • Add resistance training at least 2 days per week 4
  • Physical activity improves insulin sensitivity and helps control blood sugar 4

Weight Management:

Target 5-10% body weight reduction if overweight or obese - this produces 20% decrease in triglycerides and improves insulin sensitivity 2

Cardiovascular Risk Reduction:

If you smoke, quit immediately - smoking increases risk of cardiovascular disease and diabetes complications 1

  • Blood pressure should be maintained <130/80 mmHg 1, 2
  • LDL cholesterol goal is <100 mg/dL, or <70 mg/dL if you have heart disease 1, 3

What to Expect at Your Follow-Up Appointment

Your provider will: 1, 4

  • Review all laboratory results and determine if you have prediabetes or diabetes
  • Assess for diabetes complications (eye, kidney, nerve, heart problems)
  • Evaluate other cardiovascular risk factors (blood pressure, cholesterol)
  • Prescribe medications if needed (typically starting with metformin if kidney function is normal) 4
  • Refer you to diabetes education programs and a registered dietitian 4
  • Establish individualized blood sugar targets (typically A1C <7% for most adults) 4

Common Pitfalls to Avoid:

  • Do not wait for symptoms to develop - diabetes often has no symptoms initially, but screening and early treatment prevent complications 6
  • Do not assume you're managing diabetes well without regular testing - you cannot feel your blood sugar level or A1C 1
  • Do not stop medications without consulting your provider - even if you feel fine, stopping treatment allows blood sugar to rise and causes organ damage over time 7
