CASE 97-1

A 28-year-old woman was admitted from clinic with refractory nausea and vomiting. She has a history of long standing type 1 diabetes mellitus, which has been complicated by retinopathy and neuropathy. From a gastrointestinal standpoint, symptoms began 3 years ago with the onset of early satiety, nausea, and vomiting. This has progressively worsened despite decent glycemic control and aggressive lifestyle modification. She reports constant nausea, which is worse with food, but present to some extent even if she has had nothing to eat. She also reports vomiting after most meals—this may be as soon as minutes after eating or as long as hours. Symptoms are present with both liquids and solids and may even be worse with liquid intake. She is taking ondansetron every 8 hours and promethazine as needed in between ondansetron doses. She has attempted therapy with metoclopramide in the past but did not feel any improvement and also developed a tremor (which reversed upon stopping metoclopramide). She had an attempted solid gastric emptying study but vomited the eggs shortly after ingestion. Her liquid emptying study was markedly abnormal. Prior endoscopy showed no evidence of gastritis, peptic ulcer disease, or gastric outlet obstruction. An upper gastrointestinal (GI) series with small bowel follow-through showed delayed gastric emptying, no abnormal distention, and apparently normal small bowel transit. She has now lost 70 pounds over the past year and was admitted for evaluation, rehydration, and further management.

The patient was admitted for intravenous fluids and started on erythromycin, while being continued on the remainder of her regimen. She declined supplemental enteral or parenteral nutrition and after stabilization was discharged home. As an outpatient she was started on domperidone and seen in consultation by surgery for gastric stimulator placement, which she underwent later that year. Following gastric stimulator placement, she had a difficult postoperative recovery period and was discharged home on parenteral nutrition, which she was able to eventually taper off. She did well for a period of 3 months with marked improvement in nausea and significant weight gain, but unfortunately developed recurrent debilitating nausea and progressive weight loss, leading to a jejunal tube placement for enteral nutrition. At present, nausea remains a significant ongoing issue despite the efforts detailed here.

Nausea and vomiting are common and uncomfortable symptoms with a large number of underlying causes. Nausea is a subjective sensation, usually experienced in the epigastrium or throat when vomiting is imminent (although vomiting may or may not occur). Nausea may be followed by retching, which is repetitive active contraction of the abdominal musculature. Retching may occur in isolation without the forceful expulsion of gastric contents. In ...
