9 Side Effects of Diabetes Medicines know it all with me Dr S Jimmy 0758093842/0792423729 kololo Kampala
Diabetes medicines work in different ways, so their side effects vary by drug class. Most side effects are manageable, but some require prompt medical attention.
π£ 1. Low Blood Sugar (Hypoglycemia)
β Most common with insulin and sulfonylureas
β Signs include sweating, shaking, hunger, dizziness, confusion, or palpitations
β Treat mild episodes quickly with fast-acting glucose and review recurrent episodes with your clinician
π£ 2. Nausea, Diarrhea or Stomach Upset
β Metformin commonly causes diarrhea, nausea, or abdominal discomfort
β GLP-1 medicines can cause nausea, vomiting, constipation, or diarrhea
β Starting with a lower dose and increasing gradually often improves tolerance
π£ 3. Weight Gain
β Insulin, sulfonylureas, and thiazolidinediones (TZDs) may increase body weight
β Healthy diet, regular activity, and medication review can help limit excessive gain
π£ 4. Ge***al Fungal Infection
β SGLT2 inhibitors increase glucose in the urine, which can promote ge***al yeast infections
β Good hygiene and keeping the area dry may reduce risk
β Antifungal treatment may be needed if infection develops
π£ 5. Frequent Urination & Dehydration
β SGLT2 inhibitors cause extra glucose and water to leave through the urine
β This may cause increased urination, thirst, dizziness, or dehydration
β Maintain adequate fluids unless you have been advised to restrict them
π£ 6. Swelling of Feet or Ankles
β TZDs such as pioglitazone can cause fluid retention
β New leg swelling, rapid weight gain, or breathlessness should be reported promptly
β These drugs may be unsuitable for some people with heart failure
π£ 7. Vitamin B12 Deficiency
β Long-term metformin use can lower vitamin B12 levels in some people
β Symptoms may include fatigue, anemia, numbness, or tingling
β B12 testing and replacement may be needed when deficiency is suspected
π£ 8. Pancreatitis
β Severe persistent upper abdominal pain, often with vomiting, can indicate pancreatitis
β It has been reported with GLP-1βbased medicines, although it is uncommon
β Suspected pancreatitis needs urgent medical assessment
π£ 9. Diabetic Ketoacidosis (DKA)
β SGLT2 inhibitors can rarely cause DKA, sometimes even when blood sugar is not extremely high
β Warning signs include nausea, vomiting, abdominal pain, rapid breathing, severe weakness, or unusual drowsiness
β This requires urgent medical care
π£ General Management
β Take medicines exactly as prescribed
β Monitor blood glucose as advised
β Do not stop or change diabetes medicines without medical guidance
β Report persistent side effects, repeated low sugars, dehydration, swelling, or severe abdominal symptoms.
