The human body contains numerous bacteria that promote health, but some types are harmful because they trigger certain intestinal infections. The most common symptoms of intestinal infections are vomiting, nausea, and diarrhea.

Intestinal infection is usually caused by viruses, yeast, bacteria, mold, intestinal parasites, fungus, or perhaps poor personal hygiene. All these harmful organisms can be put in the group of pathogens. They are harmful because they infect the urinary and digestive tract and can sometimes be fatal.

Yeast infection is specific because it cannot be observed until the yeast starts converting to fungi. The conversion is usually triggered by poor dietary habits and excess ingestion of antibiotics which creates a conducive environment. The intestinal infection is usually caused by the food one ingests. The food can be affected by various types of bacteria if a person does not handle it well.

Gut Infection Symptoms

Severe abdominal cramps are one of the common symptoms of intestinal infection and they are usually caused by bacteria. Nausea is, of course, the most common of all intestinal infection symptoms, and it is a condition in which a person feels an aversion even to the most loved types of food.

Diarrhea also happens pretty often and is caused by pathogens that can be present in the intestinal tract. Diarrhea can be very dangerous because it causes dehydration, which can be severe and life-threatening.

Sometimes, the intestinal infection can lead to a loss of appetite. Intestinal infection can also trigger severe abdominal pain, and if it persists for prolonged periods one should seek immediate medical attention.

Intestinal infections can sometimes be caused by parasites present in the intestinal tract and that condition can often lead to constipation. Some types of worms are simply big enough to block the intestinal system and cause difficulties in bowel movement. Parasites can also dig into the lining of the intestinal walls to attach themselves more firmly, and by doing, so they can trigger irritable bowel syndrome. Intestinal infections can also irritate a person to the point where he or she experiences sleep disorders.

In normal conditions, the human body eliminates the toxic substances during sleep, but the parasites in the intestinal tract make it rather difficult. The pathogens draw out all the nutrients and impair the immune system, which can potentially lead to anemia. Teeth grinding may occur during the night as well.

Intestinal infections caused by yeast can also trigger depression. Among other symptoms of intestinal infection, headaches, skin rashes, and sinusitis are also worth mentioning. To avoid these types of infections one should be properly hydrated and avoid foods that are heavy to digest. Good personal hygiene is also a must.

Gastrointestinal (GI) symptoms, such as diarrhea, vomiting, abdominal pain and nausea are not an uncommon manifestation of an acute respiratory infection (ARI). We therefore evaluated clinical and microbiological factors associated with the presence of GI symptoms in patients consulting a general practitioner (GP) for ARI.
  • Nasopharyngeal swabs, stool specimens and clinical data from patients presenting to GPs with an ARI were prospectively collected during two winter seasons (2014-2016). Samples were tested by quantitative real-time PCR for 12 respiratory pathogen groups and for 12 enteric pathogens.
  • Two hundred and four of 331 included patients (61.6%) were positive for at least one respiratory pathogen. Sixty-nine stools (20.8%) were positive for at least one pathogen (respiratory and/or enteric).
  • GI symptoms were more likely declared in case of laboratory confirmed-enteric infection (adjusted odds ratio (aOR)?=?3.2; 95% confidence interval [CI] [1.2–9.9]; p?=?0.02) or human coronavirus (HCoV) infection (aOR?=?2.7; [1.2–6.8]; p?=?0.02). Consumption of antipyretic medication before the consultation seemed to reduce the risk of developing GI symptoms for patients with laboratory-confirmed influenza (aOR?=?0.3; [0.1–0.6]; p?=?0.002).
