Nausea and vomiting worse in morning

Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned with symptoms of constipation, bilious vomiting, minor abdominal pain, loss of appetite which are suggestive of intestinal obstruction. It is a mechanical or functional obstruction of the intestines, preventing the normal transit of the products of digestion. It can occur at any level distal to the duodenum of the small intestine and is a medical emergency. Depending on the level of obstruction, bowel obstruction can present with abdominal pain, abdominal distension, vomiting, fecal vomiting, and constipation.
Obstruction may be due to causes within the bowel lumen, within the wall of the bowel, or external to the bowel (such as compression, entrapment or volvulus).
Bowel obstruction may be complicated by dehydration and electrolyte abnormalities due to vomiting; respiratory compromise from pressure on the diaphragm by a distended abdomen, or aspiration of vomitus; bowel ischaemia or perforation from prolonged distension or pressure from a foreign body.
In small bowel obstruction the pain tends to be colicky (cramping and intermittent) in nature, with spasms lasting a few minutes. The pain tends to be central and mid-abdominal. Vomiting occurs before constipation.
In large bowel obstruction the pain is felt lower in the abdomen and the spasms last longer. Constipation occurs earlier and vomiting may be less prominent. Proximal obstruction of the large bowel may present as small bowel obstruction.
You must go for blood tests, X-rays of the abdomen, CT scanning and/or ultrasound. Your case seems to be that of subacute intestinal obstruction.
Some causes of bowel obstruction may resolve spontaneously; many require operative treatment.
In adults, frequently the surgical intervention and the treatment of the causative lesion are required.
Hope this helps. Take care.
