Why am I experiencing rapid weight loss?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I have a concern regarding my weight. I have lost about 2 to 2.5 kg in a month's time. I have not exercised recently. I weighed 74.4 kg last month, and now I weigh 72.8 kg. Moreover, my waist circumference has also decreased. I am worried about this sudden weight loss. Could this indicate some underlying issue?

Answered by Dr. Sadaf Mustafa

Hello,

Welcome to our portal.

  • Your BMI (body mass index) is 25.36 which is close to the normal range. However, I do understand your concern. Can you provide more details about your lifestyle as well as medical and personal history?
    • Do you smoke cigarettes? Do you have a family history of diabetes or any cancer?
      • Do you have cough, fever, chest congestion or swollen lymph nodes?
        • Have you been tested for thyroid disorders?
          • Did you have a recent episode of diarrhea? Did you experience brittle nails or hair loss?

          Revert with more information to an internal medicine physician.

Patient's Query

Hi doctor,

Thank you for replying. I do not smoke cigarettes or use any other tobacco products. I did not have diarrhea recently. I do not have hair loss, but body hair does fall often. There is no family history of heart diseases or cancer. I did not experience any chest congestion or swollen lymph nodes previously. I did not test for thyroid disorders in the past.

Answered by Dr. Sadaf Mustafa

Hi,

Welcome back to our portal.

I have the following recommendations for you:

  1. Get tested for hyperthyroidism with TSH (thyroid-stimulating hormone), free T4 and T3 tests.
  2. Rule out diabetes with HbA1c test.
  3. Rule out leukemia with CBC (complete blood count).
  4. Ensure proper functioning of liver and kidneys with CMP (comprehensive metabolic panel), UEC (urea electrolytes and creatinine) and LFT (liver function test).

Please let me know if you have got any of these investigations done and get back to us in the case of further concerns.

For further queries consult an internal medicine physician.

Patient's Query

Hello doctor,

Thanks for replying. I will get my routine check up done soon. Is my weight loss abnormal?

Answered by Dr. Sadaf Mustafa

Hello,

Welcome back to our portal.

  • Your weight loss is not abnormal. It is in a span of a month's time that you have lost the weight. It is of concern if it continues for prolonged periods, but nothing to worry for now. So I suggest you watch your weight over the next couple of months and then we could investigate further if required.
  • Weight loss is not just due to loss of fat, it could be a decrease in muscle mass as well. For example, if you lifted weights, ran or did other aerobic activities in the past and stopped now, you would still lose weight now because of a decrease in the muscle mass.
  • Do not stress about your weight loss. Explain this concern to your physician when you go for your routine check-up and also express my recommendations to him or her in your own words. Take care.

For further queries consult an internal medicine physician.
