Hello, can you list all your medication for me?
What was the antibiotic?
Any dizziness or other symptoms?
I would like you to switch from Motrin to tylenol for the headaches, motrin can irritate the stomach lining and may be adding to the problem.
Nausea was a common problem with xifaxin, although you are no longer on this. The other thing to check is whether there is any possibility of pregnancy.
Start to introduce food slowly by using soups and milkshakes for calories. You may need to have another anti-emetic such as prochlorperazine added to see if this helps.
Chronic nausea is usually a pathologic response to a variety of conditions. Gastrointestinal etiologies include obstruction, functional disorders, and organic diseases. Central nervous system etiologies are primarily related to conditions that increase intracranial pressure, and typically cause other neurologic signs. Numerous metabolic abnormalities and psychiatric diagnoses also may cause nausea and vomiting. Evaluation should then turn to identifying the underlying cause and providing specific therapies. When the cause cannot be determined, empiric therapy with an anti vomiting (antiemetic) medication is appropriate. Initial diagnostic testing should generally be done by basic laboratory tests and plain radiography. Further testing, such as upper endoscopy (done in your case) or computed tomography of the abdomen, should be determined by clinical suspicion based on a complete history and physical examination. Apart from CT scan following may be prudent;
1) Gastric emptying time
2) Stool culture
3) Liver scan
The causes of nausea can be;
A. Central nervous system
2) Space occupying lesion in brain (Mass lesion)
4) Ménière's disease
5) Pseudotumor cerebri
B. Gastrointestinal symptoms;
2) Irritable bowel syndrome
3) Non ulcer dyspepsia
4) Peptic ulcer disease
5) Cholecystitis/cholangitis (gall bladder problems)
6) Hepatitis (liver inflammation)
1) Thyroid disorders
3) Adrenal disorders
D. Psychiatry disorders
3) Conversion disorders
So, just your migraine can be responsible for the persistent nausea. Your physician may also consider blood work for thyroid and adrenal dysfunctions.
