Ulcerative Colitis Symptoms

Ulcerative colitis is a chronic condition in which symptoms vary from person to person and will range from mild to severe.

What are the signs and symptoms?

Ulcerative colitis symptoms include:

  • frequent, watery diarrhoea often containing blood, mucus and pus
  • sense of urgency to have a bowel movement (especially when the rectum is involved)
  • cramped abdominal pain (often because of constipation in unaffected parts of the colon)
  • tiredness, fatigue
  • loss of appetite
  • weight loss.

As the lining of the colon becomes more and more inflamed, it loses its ability to absorb water from the liquid waste that passes through from the ileum. This leads to watery diarrhoea, often containing mucus and pus. Among those affected, many will feel cramped abdominal pain and a strong urgency to have frequent bowel movements. It is common to feel tired and easily fatigued, especially during active phases of the disease. The tiny ulcers in the intestinal lining can easily crack open and bleed. Over time, blood loss can lead to a significant decrease in the number of red blood cells (a condition known as anaemia), which adds to the tiredness and fatigue.

It is not uncommon for those with ulcerative colitis to lose their appetite or to simply avoid eating in order to prevent further symptoms. A lack of adequate nutrition however will worsen the tiredness and fatigue and will eventually lead to weight loss. Children with ulcerative colitis might fail to develop or grow properly, particularly if they have long periods of active disease and/or receive frequent or prolonged treatment with high doses of corticosteroids (and other ulcerative colitis medications).

In addition to symptoms in the GI tract, ulcerative colitis can also cause symptoms in other parts of the body. These include:

  • red itchy eyes
  • sores in the mouth
  • swollen and painful joints
  • bumps or lesions on the skin (erythema nodosum)
  • thinning of the bones (osteoporosis)
  • kidney stones
  • a type of hepatitis called primary sclerosing cholangitis.

New study: Low carbohydrate diets could impact mortality

New study: Low carb diets could impact mortality

Low carbohydrate diets, which restrict carbohydrate in favour of increased protein or fat intake, or both, are a popular weight-loss strategy. However, the long-term effect of carbohydrate restriction on mortality is controversial and could depend on whether dietary carbohydrate is replaced by plant-based or animal-based fat and protein. We aimed to investigate the association between […]

Could Viruses Attacking The Microbiome Be Responsible For Inflammatory Bowel Disease?

New research published in Nature Microbiology suggests that viruses called phages, which infect gut bacteria may be important in controlling the disease.

New research done in a mouse model of inflammatory bowel disease (IBD) has suggested that viruses called phages, which have the ability to infect and kill gut bacteria, may be involved in the disease. The possible role of the microbiome in inflammatory diseases has been a busy area of research recently, with a study in May showing […]

IBD, steroid use increases influenza risk

Patients with inflammatory bowel disease have a higher risk for influenza and are more likely to be hospitalized because of it, according to research published in Inflammatory Bowel Diseases. Andrew Tinsley, MD, of the division of gastroenterology and hepatology at The Pennsylvania State University Hershey Medical Center, and colleagues wrote that their findings highlight the importance of vaccinating patients […]

BPA risk factor for inflammatory bowel disease?

BPA risk factor for inflammatory bowel disease

A recent study in a preclinical model of inflammatory bowel disease shows dietary exposure to bisphenol-A, or BPA, found in polycarbonate plastics and epoxy resins, can increase mortality and worsen its symptoms. Dr. Clint Allred, a Texas A&M AgriLife researcher in the nutrition and food science department at Texas A&M University in College Station, led […]

Are your gut feelings controlling your mood?

Posted: June 28 2018

Many of us are painfully aware of the feeling of a “gut-wrenching” experience, or having “butterflies in your stomach”, so it comes as no surprise that our emotions and thoughts affect our digestion. Interestingly though, the gut has a larger role to play in our mental-emotional state than we might have realized. Research is still […]

New vitamin supplement study finds they may do more harm than good

A new study aimed to examine the benefits of vitamin and mineral supplements for prevention of heart disease, stroke and premature death (termed “all-cause mortality”). This found the most commonly studied ones had no effect, while some less common ones did have an effect.

In Australia’s most recent nutrition survey, 29% of people reported having taken at least one dietary supplement. This proportion was even higher in the United States at 52%. A new study out today aimed to examine the benefits of vitamin and mineral supplements for prevention of heart disease, stroke and premature death (termed “all-cause mortality”). This found the most commonly studied […]
