Gastrointestinal Bleeding: Signs, Causes, Remedies, and Healing Process
In the realm of health, understanding chronic lower gastrointestinal (GI) bleeding is crucial for maintaining one's wellbeing. This article aims to shed light on the common causes, symptoms, and treatments associated with this condition.
Chronic lower GI bleeding, characterised by slow, intermittent blood loss, can lead to anemia, occult bleeding detected by fecal tests, or intermittent visible bleeding (melena or scant hematochezia). The most frequent causes of this condition are diverticulosis, hemorrhoids, and inflammatory bowel disease (IBD), although other factors such as colorectal polyps or cancer, vascular abnormalities like angiodysplasia, and bleeding disorders may also play a role [1][2][4][5].
Diverticulosis, a condition that affects the large intestine, accounts for up to 40–60% of cases, while hemorrhoids, a common condition that causes swollen veins in the rectum or anus, contribute near 20% in some cohorts [1][2][3][5]. IBD, which includes Crohn's disease and ulcerative colitis, also significantly contributes, causing chronic mucosal inflammation and bleeding [1][2][4].
Treatment for lower GI bleeds depends on the cause and severity. For instance, hemorrhoids and anal fissures may respond to conservative measures like dietary fiber and topical treatments, while office-based procedures may be necessary [1]. Diverticular bleeding is often managed conservatively as it frequently stops spontaneously; however, recurrent or severe bleeding may require endoscopic intervention or surgery [2][5]. IBD is treated with anti-inflammatory medications, immunosuppressants, and biologics to control inflammation and bleeding [1][2][4].
Angiodysplasia, a condition characterised by abnormally large or swollen blood vessels in the digestive tract, may be treated with endoscopic coagulation techniques or, rarely, surgery [4][5]. Colorectal polyps and cancers require removal via endoscopy or surgery and oncologic management if malignant [1][4].
Bleeding disorders, such as Von Willebrand's disease, can also cause lower GI bleeds. Although there is no cure for these disorders, medications may help reduce symptoms [3].
It's important to note that lower GI bleeds are responsible for about 50% of all GI bleeding events in Western countries [5]. Factors that may increase the risk include age, overuse of nonsteroidal anti-inflammatory drugs, chronic constipation, family history of conditions that damage the lower GI tract, blood or bleeding disorders, and activities that could potentially cause rectal tears.
The recovery time from GI bleeds depends on the cause and how early a doctor diagnoses and treats it. In most cases, more than half of lower GI bleeding events resolve on their own, but this can depend on the cause [5]. However, severe or continuous lower GI bleeding can cause symptoms associated with shock, such as little to no urination, rapid pulse, reduced blood pressure, cold hands and feet.
In summary, chronic lower GI bleeding is a multifaceted condition with various causes, symptoms, and treatments. By understanding these aspects, individuals can take proactive steps towards maintaining their gastrointestinal health. If you experience sudden and unexplained blood in your stool or vomit, it's essential to seek medical attention.
