Dear customer
Welcome to and thank you for your question.
I'm so sorry to hear of your discomfort. I will do whatever I can to help answer your questions
Yes,the symptoms you are having can be due to a condition called gastroenteritis what you call as stomach flu. Gastroenteritis is the irritation and inflammation of the digestive tract.
Its most common causes are:Food poisoning, viral infections, food allergies, improper diet, and intestinal parasites or bacterial infections.
The tiredness,lethargy,sleeping constantly,loss of appetite,gas can be due to this food poisoning/parasite/bacterial infection.
Although you had a Ct scan. chest Xray, & a Barium X-ray with normal reports other then barium results awaited,I advise you to make an appointment with your gastro doctor to have stool test & a colonoscopy.Antibiotics may be prescribed accordingly.
Till then take tab meclizine hydrochloride(brand name: Dramamine).This will help you greatly in stopping the nausea & vomiting.Take tab.Ranitidine(Zantac) 150 mg twice a day to get relief from gastric trouble/gas.
Hope this helped.
My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back, I am happy to address follow-up questions.
Thank you *****

Hi there,

I would like to add my opinion here if you do not mind.

With constipation, weight loss of 15 kg, the first thing that I would like to rule out is something potentially serious like cancer of the colon which can present with constipation and can cause one to have weight loss like what you are having.

Weight loss of this degree is very significant to say the least.

The encouraging thing is that the CT scan is normal but an upper and lower GI endoscopy is absolutely essential in your case.

A barium enema is also something that could point to a diagnosis.

I personally think that with constipation you are UNLIKELY to be having gastroenteritis as stated by the expert above. With gastroenteritis one would also be having diarrhea which you are not having.

Also I would recommend that you should have your thyroid hormones checked if you have not had those already because at your age thyroid problems can present with wierd symptoms and a thyroid problem must be ruled out by doing a thyroid function test. I would appreciate it if you rate me by clicking on one of the rating options below.

This session is open for any number of further questions that you may have.

Kind regards
