Hello, I am 40, male, non-smoker, 6ft tall and weighing 194lbs. I ve been losing weight for the past 5 months. In March I went to my cardiologist to have my heart checked. Since then I am on Lisinopril 20mg to control my bloodpressure. All the tests were fine. At the time of my doctors visit I was weighing 230lbs. So I dropped around 36 pounds in 5 months. Is that normal? Also, it doesn t stop. I keep losing weight. I changed my diet a little bit, but nothing radical though. Less soft drinks and deep fried food, other than that I have decent lunch and dinner. I don t have any pain or loss of appetite. My bowel movement is normal and stool color is light-brown to brown. Could Lisinopril be the cause of my weight loss? Also, I have anxiety and get very nervous with the slidest pain. Could anxiety also be a cause? Your thoughts and comments are more than welcome. Many thanks Michael

H, I passed carefully through your question and would explain that your symptoms do not seem to be related to lisinopril, as this is not a common adverse effect related to this Chat Doctor.  Coming to this point, I would recommend consulting with your attending physician and performing some tests to investigate for the possible underlying causes: - complete blood count for anemia- PSA, Ca19.9 and CEA plasma levels- an abdominal ultrasound - a chest X-ray study-vitamin B12 plasma levels for possible deficiency. You should discuss with your doctor on the above tests. Hope I have answered your query. Let me know if I can assist you further.
