I am a 41-year-old man with a strong family history of diabetes. I was diagnosed nine months ago after a random blood sugar of 290 mg/dL and fasting blood sugar of 250 mg/dL.
Glucophage 500 mg twice daily reduced my random readings to 100–130 mg/dL and fasting readings to 90–125 mg/dL. However, my weight fell from 76 kg to 65 kg in six months.
Three months ago, I stopped Glucophage and replaced it with Karela, or bitter gourd, tablets. My random readings are now 110–135 mg/dL and fasting readings are 95–120 mg/dL, but my weight remains 65 kg.
Should I continue Karela? Is my weight related to the treatment? I avoided sweets while taking Glucophage but now eat some sweets while taking Karela.
Do not use Karela as a replacement for Glucophage without medical advice. Bitter melon may lower blood sugar, but evidence is not strong enough to show that it can reliably replace metformin. Your 11 kg unintentional weight loss also needs medical evaluation.

Dear Sameh,
Your readings appear much better than at diagnosis, but stopping a prescribed medicine and replacing it with a supplement should be reviewed by your doctor. Home readings alone cannot confirm that your diabetes is fully controlled.
Karela, also called bitter melon or bitter gourd, has been studied for possible blood-sugar-lowering effects. Results are inconsistent, and herbal tablets can vary in strength and purity. They do not have the same predictable dosing or long-term evidence as metformin.
Do not restart Glucophage, increase Karela, or combine them without professional advice. Take the supplement package to your doctor or pharmacist so the exact ingredients and dose can be checked.
For many adults with diabetes, common targets are 80–130 mg/dL before meals and below 180 mg/dL one to two hours after starting a meal. Individual targets may differ.
Your fasting readings of 95–120 mg/dL may be within a reasonable treatment range. However, a random reading is difficult to interpret unless you record when it was taken in relation to food.
You should have an HbA1c test. It estimates average glucose over approximately three months and may detect higher readings that occasional finger-prick tests miss.
Metformin can cause modest weight loss in some people, especially when appetite or food intake decreases. However, losing 11 kg should not automatically be blamed on Glucophage.
Possible causes include reduced calorie intake, uncontrolled diabetes before treatment, loss of muscle, thyroid disease, digestive illness, or another medical condition. Adult-onset type 1 diabetes can also initially resemble type 2 diabetes.
Ask your doctor whether you need HbA1c, kidney function, thyroid tests, and evaluation of the weight loss. If the diabetes type is uncertain, C-peptide or diabetes antibody testing may be considered.
No. Sweets may raise blood sugar without providing the protein and nutrients needed to restore healthy weight. If you need to gain weight, use balanced meals containing protein, vegetables, higher-fiber carbohydrates, dairy or alternatives, nuts, seeds, olive oil, and other nutrient-dense foods.
Seek urgent care for vomiting, abdominal pain, rapid or deep breathing, severe dehydration, confusion, fainting, positive ketones, or persistently very high glucose.
No. Current evidence does not show that bitter melon can reliably replace prescribed diabetes medicine.
It may cause modest weight loss, but substantial or continuing unintentional weight loss should be investigated.
It may be within a common treatment target, but HbA1c and after-meal readings are also important.
