<s>[INST] I had a Nissen Fundoplication 4 years ago, whenever I get a stomach bug I am ill for 1 week, At the moment I have been poorly for 5 days. I had been on holiday to Lanzarote and was back for 36 hours when I started with intense nauseau, diarrhoea, fever , palpitations and initially a dull ache in my right side. For the first 24 hours I thought I may have had appendicitis although the ache in the right side eased off and did not become any worse, I felt too ill to get out of bed. Since then I feel weak, nauseaus, headache , no appetite , when I do eat I feel sick again, I have no energy, I am now tolerating fluids but still feel really ill and I need to get better to return to work, help! [/INST] Hi Karen, Thanks for writing in. I think what you suffered from was infectious diarrhoea and you are definitely on your way to getting better. As of now, you'd be better if you take plenty of fluids ( particularly oral rehydration solution or Gatorade) and light home cooked food. Eating small amounts at small intervals will help. Also, a course of antibiotics like ciprofloxacin would greatly help. Please speak with your physician about this. You don't need any other treatment as of now and I think you should be back on your feet with this in 1-2 days. Hope this helps. </s>
