Thank you for the query.
Such symptoms can be caused by stomach or duodenum ulcers. The pain is usually located in the upper middle abdomen. Chest burning or acid reflux
can be present. Soft drinks can have some impact on it.
It is advisable at your case to have some tests. Abdominal ultrasound
, full blood work and upper GI endoscopy
should be performed with Helicobacter Pylori
Hope this will help.
