Ask Health Experts and Get Answers to Your Health Question ASAP
I fully understand your fears and concerns and will try to help you. You have described that your husband has a complex medical history incuding respiratory illness and diagnosis. This would indicate that he would not have a 'normal' chest x-ray, but instead, one showing the typical changes that indicate COPD and emphysema.
Since his appetite is decreased, it makes sense that he is losing weight, and the question is, why? Therefore the doctor will do medical investigation to rule out any problem. If a cause for his symptoms is found, then it can be treated so he can feel better. You are overly 'scared' because of your past experience, and that is absolutely understandable. Right now there is no diagnosis and that can be a good thing. They may find nothing at all, but they must look in order to know that. When you say upper and lower CT of chest, I am wondering if you mean upper and lower GI series which would be done for his symptoms to make sure all is well in his stomach and bowels. They will look for any irritation of gastric lining, ulcers, tumors, polyps. I am glad to know that his blood work is within normal limits and that is a good first step.
I wish your husband well!
Please let me know when his test is scheduled for and if I can help you any further.
You should call the doctor and clarify exactly what test will be done and what SHE is looking for. This will reduce your anxiety if the doctor would discuss with you.
Let me know what the test is as soon as you find out.
Thank you very much!
Thank you for the extra added detail. A CT scan is more detailed than a regular xray and can help the doctor determine diagnosis, by producing multiple images and pictures along with the help of a computer. Let's face it, your husband has smoked for thirty years and you know that there are lung risks involved with smoking and the doctor wants to look for changes in the lungs related to that. I don't know your hubby's entire medical history so I base my answer on what you have told me. This test can help diagnose clinical symptoms of disease of the chest (you said he has COPD and emphysema). A chest CT can also show other lung disorders such as pneumonia, bronchiectasis, inflammation or diseases of the pleura (membrane covering the lungs.
A CT scan of the abdomen is typically done to help diagnose the cause of abdominal pain. It is very good that your doctor is searching for a cause of your husband's symptoms because then he can be treated properly. This test can be used to study blood vessels, detect masses and tumors and look for infection, kidney stones. It shows detailed pictures of the belly area.
Of course you will be apprehensive while waiting for results but please realize that this is being done to benefit him. We tend to think the worst. Ignoring the symptoms is of no use.
I hope I have helped you.
You and your husband are in my prayers.
Let me know if you want to talk further.
