My elastase is 3, I lost a lot of weight and the doctor prescribed me Creon.

Thank you for sharing your case. The reference values for pancreatic elastase are above 200 μg/g of faeces. The single-digit result is invalid. I understand that you are currently under severe stress about the outcome and suspicion of pancreatic disease. However, it is best to talk about these concerns directly with your doctor, who has more information about your health condition and will be able to tell you more about the prognosis, i.e. the prospects for the course of treatment. From a pharmaceutical point of view, I can explain that you have received treatment at the moment, consisting in the substitution (supply from the outside) of pancreatic enzymes. Doing so will help you digest food and should also have a positive effect on your body weight, as you will be able to reabsorb nutrients from food. It is worth getting acquainted with the recommendations for taking Kreon correctly available in the leaflet (m.in the preparation is taken with a meal).
