Gastroenteritis, or commonly (and mistakenly) known as the stomach flu, is an inflammation of the lining of the stomach and small and large intestines. Most of the cases are infectious, although gastroenteritis may also follow ingestion of drugs and chemical toxins (eg, metals, plant substances).
Infectious gastroenteritis is commonly caused by viruses (Rotavirus, Norovirus, Astrovirus, Adenovirus, CMV), and less commonly by bacterias (Campylobacter, Salmonella, Shigella, E.coli O157:H7) and parasites (Giardia, Cryptosporidium).
Generally, there is a sudden onset of symptoms, with anorexia, nausea, vomiting, borborygmi, abdominal cramps, watery diarrhea (with or without blood and mucus), malaise, myalgias, and prostration. The abdomen may be distended and mildly tender; in severe cases, muscle guarding may be present. Gas-distended intestinal loops may be palpable. Borborygmi are present even without diarrhea. Persistent vomiting and diarrhea can result in intravascular fluid depletion with hypotension and tachycardia. In severe cases, shock, with vascular collapse and oliguric renal failure, occurs.
Treatment is symptomatic, although parasitic and some bacterial infections require specific anti-infective therapy. Gastroenteritis is usually uncomfortable but self-limited. Electrolyte and fluid loss is usually little more than an inconvenience to an otherwise healthy adult but can be grave for people who are very young elderly, or debilitated or who have serious concomitant illnesses.

This was what I had last weekend. A rather bad case of gastroenteritis. First it was diarrhea. I thought it was just a plain case of lactose intolerance (had a glass of milk Friday afternoon) which usually would pass after a few hours, or at least food poisoning. But then the symptoms got worse; non-stop diarrhea, nausea, abdominal cramps, a pulsating frontal headache, back pain and muscle cramps. And come Saturday afternoon my temperature spiked! I was dehydrated from the diarrhea and had chills all over that I couldn't eat anything. All I could managed was sipping plain lukewarm water then and again, swallowing a couple of tabs of PCM, gulping down home-made ORS (oral rehydration salt) mix, wrapping up myself under the blankets, and slept and slept and slept...
Alhamdulillah, the next morning the fever, headache, cramps, nausea were all gone. Still had some mild diarrhea though. All I could manage was some dry toasts and soup. By nightfall I was almost normal, albeit a little bit weak. I was lucky that my recovery was speedy, I guess that my decision to rehydrate and control the fever worked in my favour. That and also the fact that although the urge to vomit was there I tried not to because I knew that if I do I'm gonna be more dehydrated. It may be bad to suppress the urge, but I do know my body well and how it reacts.
Until now I have been trying to figure out what had caused it. The only conclusion that I can come up with is that I may have had a viral gastroenteritis contracted from the hospital or from my colleagues. Why? Because apparently some of my classmates also fell ill with almost the exact same symptoms that I had on the very same day. It definitely wasn't food poisoning because we didn't eat the same food. Coincidence? I think not. Although, according to one of the doctors it could also be the fact that there was an epidemic of stomach flu at the time. And I think he could be right, because of this. Whatever it was, it affected my friends worse than me. Poor things. But as Ms MCL said there is an upside to it; she lost 5 pounds in less than a week! Good for her, but caution to all of you especially the bulimics: vomiting is NEVER the solution to weight loss, comprende?
It's been a long while since I was this sick. Thank goodness I keep some PCMs, aspirins, charcoal tablets, and paid attention during physiology class. Time and again the ORS mix proved to be useful when no pre-packed ORS are available on-hand. Thanks Prof. Ruby, you're a life saver!
n.b. I'm laying off rice for now. My stomach can't seem to stand it anymore, too starchy I guess. Might go vegetarian for a while. Wonder how long till I'll start craving for some meat...
