Ovarian cancer originates in the ovaries, small, oval-shaped organs located in the pelvis. This cancer is challenging to detect early because its initial symptoms are often subtle and easily mistaken for common, less serious conditions. Understanding how this disease manifests is important for timely diagnosis. This article explores the relationship between ovarian cancer and digestive changes, particularly constipation, and outlines other important symptoms to recognize.
The Direct Link: Ovarian Cancer and Bowel Changes
Ovarian cancer can cause constipation and other forms of gastrointestinal distress. Changes in bowel habits, including new or worsening constipation or diarrhea, are recognized symptoms associated with the disease. These digestive issues are often part of vague abdominal symptoms that are easily dismissed by patients and healthcare providers.
The subtle nature of these symptoms is a major reason why ovarian cancer is often diagnosed at a later stage. The initial signs often mimic common digestive disorders like irritable bowel syndrome (IBS). Cancer-related bowel changes, however, tend to be persistent, meaning they do not come and go, and represent a change from a person’s normal health baseline.
When bowel changes appear alongside other abdominal symptoms, an underlying gynecological issue may be the cause. The ovaries are situated near the large and small intestines, which explains why a growing mass can directly affect digestive function.
Physical Mechanisms of Bowel Interference
Constipation is primarily related to the tumor’s growth and spread within the abdominal cavity. One direct cause is the mass effect, where the tumor physically presses on nearby sections of the colon or rectum. This external compression narrows the passage, restricting the movement of stool and leading to difficulty passing waste.
Fluid buildup in the abdomen, known as ascites, also contributes to bowel dysfunction by creating widespread pressure on abdominal organs. As this fluid accumulates, it causes abdominal distention, which squeezes the intestines and slows down their normal muscular contractions, or motility. This external pressure slows the transit time of food and waste, exacerbating constipation.
In advanced cases, the cancer may spread to the peritoneum, the lining of the abdominal cavity. This metastatic spread can cause inflammation and functional changes in the bowel wall, further slowing the digestive process. Certain treatments, such as pain medications, can also slow the gut and cause constipation as a secondary side effect.
Recognizing Other Common Ovarian Cancer Symptoms
Constipation is typically part of a broader set of changes experienced by those with ovarian cancer. The most frequently reported symptom is persistent abdominal bloating or swelling that does not fluctuate or resolve, unlike temporary bloating experienced after meals or during the menstrual cycle. This persistent bloating is a key indicator that warrants medical attention.
Another common sign is persistent pelvic or abdominal pain, often felt as a dull ache or pressure in the lower stomach or pelvis. This discomfort is typically ongoing rather than cyclical or temporary. Patients may also notice early satiety, a feeling of fullness after eating only a small amount of food, or general difficulty eating.
Changes in bladder habits are also frequently reported due to the proximity of the ovaries to the bladder. This can manifest as increased urgency or needing to urinate more frequently than normal. These symptoms are more suggestive when they are new, occur daily, and persist for several weeks or more.
Actionable Steps and Early Detection
Since there is currently no routine screening test for ovarian cancer, awareness of symptoms is the most important tool for early detection. Any individual who experiences new or worsening symptoms—including persistent constipation, bloating, pain, or urinary changes—that last for two to three weeks should schedule an appointment with a healthcare provider. Tracking the frequency and severity of these symptoms before the visit provides the most accurate information.
During the consultation, mention specific concerns about ovarian cancer, especially if there is a family history of ovarian or breast cancer. Early-stage diagnosis is linked to significantly better survival rates, making prompt evaluation essential. Consulting a medical professional is the only way to determine the underlying cause of persistent digestive or abdominal changes and to rule out serious conditions.
