The stomach flu, and its accompanying symptoms such as vomiting, fever and diarrhea, can make you miserable. Fortunately, it is almost always self-limiting and most people recover fully without any treatment.

However, if you get sick from a stomach infection, there are important steps that you need to take to help increase the probability that you will experience a rapid and complete recovery. Why the necessity?

Experiencing an acute gastrointestinal infection raises your risk of developing ongoing digestive symptoms, a condition called post infectious IBS (IBS-PI). Follow these simple guidelines to reduce your risk.

Get Rest

Seems easy enough, but face it -- many of us decide we are too busy to take proper care of ourselves. You may need to re-think this. One well-designed study found a clear link between activity level and the later onset of IBS. Patients who developed IBS following an acute GI illness were less likely to rest in response to initial symptoms and more likely to remain active throughout the course of the illness.

Don’t Suppress Vomiting

In a classic Seinfeld episode, Jerry speaks proudly of his no-vomiting record. Don’t follow his lead. Vomiting is part of the body’s own defenses against foreign invaders such as viruses and bacteria. In studies of one specific bacteria, patients who experienced vomiting during the acute stage of their illness had their risk of developing IBS-PI reduced by half.

Stay Hydrated

When you have a stomach infection, staying hydrated can help you feel better--and recover--faster. Through vomiting and diarrhea, vital fluids are lost and need to be replaced. Choose clear liquids and those with electrolytes, but make sure to avoid sugary and caffeinated drinks as these can worsen diarrhea.

If it is difficult to keep fluids down, take very small but frequent sips or suck on ice chips. 

Keep Your Stress Level Low

Research is consistently finding a relationship between high levels of anxiety and stress around the time of the initial illness and the risk of ongoing symptoms. It is thought that this relationship might extend for up to three months before the onset of the illness. Although we may have little control over the stressful events that pop up in our lives, using active relaxation and stress management strategies can help to reduce the effect that the outside stress has on our insides.

Think Happy Thoughts

As far-fetched as it may seem, what we think can affect how we feel. Patients who are pessimistic about their illness and their symptoms appear to be at higher risk for ongoing problems. If you get ill, think positive thoughts about your illness. Talk to yourself like a loving parent, reassuring yourself that you will be “all better soon.”
