Inflammatory Bowel Disease (IBD)
Irritable Bowel Syndrome (IBS)
Systemic sclerosis (scleroderma) can cause constipation, diarrhea, collagenous colitis, irritable bowel syndrome (IBS), malabsorption, diminished peristalsis, and bowel incontinence. It can also overlap with Crohn's disease and ulcerative colitis.
Typical in the initial stages of scleroderma is chronic constipation, sometimes alternating with diarrhea. Late stage scleroderma bowel involvement is often marked by diarrhea, malabsorption, and bowel incontinence.

Intestinal microbiome in scleroderma (SSc): recent progress. Emerging evidence suggests that alterations in gut microbiota exist in the SSc disease state and more studies are needed to ascertain the mechanism by which these alterations perpetuate inflammation and fibrosis in SSc. PubMed, Curr Opin Rheumatol, 2017 Nov;29(6):553-560. (Also see Endocannabinoid System)
Lactose malabsorption in systemic sclerosis. Our findings highlight the fact that lactose breath test is a helpful, non–invasive method, by identifying the group of patients with systemic sclerosis with symptomatic lactose malabsorption that may benefit from a reduction in lactose intake. PubMed, Aliment Pharmacol Ther, 2016 Nov;44(10):1123-1133.
Endocannabinoids in the Gut This review highlights research that reveals an important role for the endocannabinoid system in the control of a variety of gastrointestinal functions. PMC, Cannabis Cannabinoid Res, 2016; 1(1): 67–77. (Also see Endocannabinoid System)
Systemic Sclerosis Patients Found To Have a Unique Colon Microbiota. The team concluded that patients with systemic sclerosis have an imbalance in their colon microbiota. They suggest that alterations in the gut may contribute to the disease symptoms, and could be potentially used in the diagnosis of systemic sclerosis as well as in the development of alternative therapeutic strategies. Scleroderma News, 06/12/2015.
Peristalsis: Scleroderma can cause diminished peristalsis. Peristalsis is the wavelike motion in the muscles of the GI tract.
Abdominal distention is a common condition, which usually results from over-eating, rather than from a serious illness. It can also be caused by lactose intolerance, air swallowing, irritable bowel syndrome, and partial bowel obstruction. Medline Plus.
Constipation treatments include increasing fiber, water and activity; bulking agents, softening agents, and stimulants.
Scleroderma patients with constipation should consult their scleroderma expert for treatment, because reduced motility can make increased fiber or bulking agents hazardous or even fatal. (Also see: What is Scleroderma?)

Efficacy of anorectal biofeedback in scleroderma patients with fecal incontinence (FI): a case–control study. Patients with scleroderma benefit from biofeedback therapy to the same extent as that achieved in patients with functional FI. PubMed, Scand J Gastroenterol, 2016 Dec;51(12):1433-1438.
Clinical correlates of faecal incontinence (FI) in systemic sclerosis (SSc): identifying therapeutic avenues. Other than targeting anorectal dysfunction, concomitant treatment of clinical correlates could lead to improvement in FI and quality of life in SSc. PubMed, Rheumatology (Oxford), 12/24/2016.
Eating 1 to 2 tablespoons a day of live culture acidophilus yogurt may be helpful for combatting bowel involvement with systemic scleroderma, especially small bowel bacterial overgrowth. It may also be particularly helpful when taking antibiotics. It has the additional benefit of being nutritious and easy to swallow. Only a very few brands/types of yogurt (especially in the U.S.) have live cultures, so study product labels carefully.

Endocannabinoid system acts as a regulator of immune homeostasis in the gut. Our study unveils a role for the endocannabinoid system in maintaining immune homeostasis in the gut/pancreas and reveals a conversation between the nervous and immune systems using distinct receptors.

Ileostomy, Colostomy, and Ileoanal Reservoir Surgery. Sometimes treatment for Crohn's disease, ulcerative colitis, and familial adenomatous polyposis involves removing all or part of the intestines. NDDIC.
Sandy J: CREST Scleroderma I have had an ileostomy for two years and a feeding peg for just over one year, and would appreciate comments from any person who also has one or both of these problems…
Habba Syndrome Symptoms, Diagnosis and Treatment. This is chronic diarrhea that predominately occurs after meals, for at least three months. Diarrhea is often urgent, explosive, and may result in incontinence. VeryWell.
Intestinal Pseudo-Obstruction Intestinal pseudo-obstruction (false blockage) is a condition that causes symptoms like those of a bowel obstruction (blockage). Symptoms include cramps, stomach pain, nausea, vomiting, bloating, fewer bowel movements than usual, and loose stools. Diseases that affect muscles and nerves, such as lupus erythematosus, scleroderma, or Parkinson's disease, can cause symptoms. NIDDK
Intestinal pseudo–obstruction in patients with systemic sclerosis: an analysis of the Nationwide Inpatient Sample. Intestinal pseudo–obstruction is a rare cause of hospitalization in patients with SSc, but is associated with high in–hospital mortality in comparison with other SSc patients and those with intestinal pseudo–obstruction secondary to other causes. PubMed, Rheumatology (Oxford), 2016 Apr;55(4):654-8.
A new method for evaluation of intestinal muscle contraction properties: studies in normal subjects and in patients with systemic sclerosis. Systemic sclerosis patients had increased stiffness and impaired muscle dynamics of the duodenum. Decreased muscle function and increased wall stiffness may explain the GI symptoms reported in this patient group. PubMed, Neurogastroenterol Motil. (Also see Gastrointestinal Involvement)
Prevalence and associated factors of small intestinal bacterial overgrowth (SIBO) among systemic sclerosis (SSc) patients. The prevalence of SIBO, using the glucose H2 /CH4 breath test, is not common, however a positive result was associated with longer duration of disease. PubMed, Int J Rheum Dis, 02/06/2019.
Treatment of small intestinal bacterial overgrowth (SIBO) in systemic sclerosis (SSc): a systematic review. For some SSc patients, antibiotics can eradicate SIBO and there is a paucity of data reporting the effectiveness of either prokinetics or probiotics in SSc. PubMed, Rheumatology (Oxford), 07/02/2018.
Microbial and metabolic multi–omic correlations in systemic sclerosis (SSc) patients. Our data suggest that in SSc, intestinal microbiota is characterized by proinflammatory alterations subtly entwined with the metabolic state. PubMed, Ann N Y Acad Sci, 05/11/2018.
Intestinal microbiome in scleroderma (SSC): recent progress. Therapeutic trials are needed to investigate whether dietary interventions or fecal transplantation can restore the gut microbial balance and improve health outcomes in SSc. PubMed, Curr Opin Rheumatol, 07/15/2017
Intestinal dysbiosis is common in systemic sclerosis (SSc) and associated with gastrointestinal and extraintestinal features of disease. Intestinal dysbiosis was common in patients with SSc and was associated with gastrointestinal dysfunction, malnutrition and with some inflammatory, fibrotic and vascular extraintestinal features of SSc. PubMed, Arthritis Res Ther, 2016 Nov 29;18(1):278.
Systemic sclerosis (SSc) is associated with a unique colonic microbial consortium. This study demonstrates a distinct colonic microbial signature in SSc patients and this unique ecological change may perpetuate immunological aberrations and contribute to clinical manifestations of SSc. PubMed, Arthritis Rheumatol, 01/08/2016.
Systemic Sclerosis Patients’ Intestinal Microbiome Found To Be Enriched by Inflammatory Bacteria. Patients with systemic sclerosis harbor a unique microbiome in their gut when compared to healthy individuals, which may contribute to patients’ immune dysfunction. Scleroderma News, 06/17/2015.
Inflammatory Bowel Disease (IBD) should not be confused with Irritable Bowel Syndrome (IBS) which is less severe. In particular, collagenous colitis should be suspected in systemic scleroderma patients who develop watery diarrhea. ISN.

Overlap of symptoms of gastroesophageal reflux disease (GERD), dyspepsia (FD) and irritable bowel syndrome (IBS) in the general population. GERD, FD and IBS are common conditions in the general population and the overlap between these conditions is also quite common. PubMed, Scand J Gastroenterol, 2015 Feb;50(2):162-9. (Also see Reflux and Scleroderma Heart Involvement)
Sympathetic nervous system dysfunction in fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome, and interstitial cystitis. Sympathetic dysfunction could be the common underlying pathogenesis that brings on these overlapping clinical features. PubMed, J Clin Rheumatol.

Irritable Bowel Syndrome. Up to one in five American adults has irritable bowel syndrome (IBS). For most people, signs and symptoms of IBS are mild. In many cases, you can control irritable bowel syndrome by managing your diet, lifestyle and stress. MayoClinic.
Scleroderma can cause malabsorption, which is difficulty in the digestion or absorption of nutrients from food substances.
"Malabsorption caused by medical problems may be chronic and last for the remainder of a person's life. Some forms of malabsorption can be treated and corrected over time." University of Chicago
Systemic scleroderma can cause diminished peristalsis. Peristalsis is the wavelike motion in the muscles of the gastrointestinal tract.
(Expired Article) Almost every patient with scleroderma has symptoms or signs of gastrointestinal disease. Bloating, abdominal distention, diarrhea, bacterial overgrowth, weight loss, and constipation are common. Recurrent bouts of pseudo-obstruction are one of the most serious bowel problems in scleroderma. Medical Books Online.
