Digestive issues are often easy to overlook, especially when the symptoms seem mild or temporary. A stomachache, for instance, may be easily dismissed as something that will pass on its own after some rest. While many minor digestive problems do improve without medical treatment, persistent or recurring symptoms sometimes point to an underlying condition that needs closer attention. When this happens, consulting a healthcare professional can help determine what’s causing the problem and whether further investigation is necessary.
One procedure doctors may use to examine the digestive tract is an endoscopy. This medical procedure uses a thin, flexible tube with a camera, allowing a doctor to look inside the body through an opening such as the mouth or nose. What does endoscopy detect? It can help identify various digestive issues, sources of bleeding, inflammation, and other abnormalities that may not be apparent from symptoms alone.
But how can you tell when what you’re experiencing may warrant an endoscopy? In this article, we’ll discuss some digestive symptoms that may prompt a healthcare professional to recommend one.
1. Persistent or Recurring Stomach Pain
Stomach pain that doesn’t go away or keeps coming back may need further investigation, particularly when its cause isn’t clear. While occasional discomfort can have a simple explanation, ongoing pain may be linked to an underlying digestive condition.
An endoscopy allows a doctor to examine the upper digestive tract for problems such as ulcers, inflammation, irritation, or other abnormalities. If necessary, tissue samples can also be taken for further testing. The findings can help healthcare professionals determine whether medication, dietary changes, or further treatment may be appropriate.
2. Difficulty or Pain When Swallowing
Difficulty or pain when swallowing can sometimes be linked to problems affecting the oesophagus. Mild or temporary episodes may have a straightforward cause, but symptoms that persist or become worse may warrant medical assessment.
By providing a direct view of the oesophagus, an upper endoscopy can help identify inflammation, narrowing, or other abnormalities. If a problem is identified, the procedure may also be used as part of treatment, such as widening a narrowed section of the oesophagus, when appropriate.
3. Frequent or Severe Heartburn
Occasional heartburn is common, but frequent or severe episodes may indicate an underlying digestive problem that requires closer attention. This is particularly relevant when heartburn persists despite lifestyle changes or recommended treatments.
Examining the oesophagus and stomach with an endoscope can help a doctor check for irritation, inflammation, ulcers, or damage associated with acid reflux. The findings can guide treatment and may also reveal complications that need to be monitored or managed.
4. Unexplained Nausea or Vomiting
Nausea and vomiting can occur for many reasons, including short-term illnesses or dietary issues. However, symptoms that don’t have an obvious cause or continue over time may require further investigation, especially when they interfere with eating or drinking.
In these cases, examining the upper digestive tract can help reveal potential causes, such as inflammation, ulcers, blockages, or other abnormalities. Depending on the findings, treatment may involve medication, dietary adjustments, or additional investigations.
5. Gastrointestinal Bleeding
Blood in the vomit or stool can be a sign of bleeding in the digestive tract and should be assessed by a healthcare professional. The appearance of the blood can vary depending on where the bleeding occurs, so further investigation may be needed to identify its source.
In cases of suspected gastrointestinal bleeding, an endoscopy can help locate the source and identify possible causes, such as ulcers or abnormal growths. In some cases, the doctor may also use the procedure to control or stop the bleeding, making it useful for both diagnosis and treatment.
6. Unexplained Weight Loss
Losing weight without intentionally changing your diet or exercise routine can sometimes point to an underlying health issue. When unexplained weight loss occurs alongside digestive symptoms, a doctor may recommend further testing to determine the possible cause.
Examining the digestive tract can help identify abnormalities that could contribute to unexplained weight loss. If an unusual section is found, the doctor may take a biopsy so it can be examined more closely. The results can then help determine what treatment or follow-up is needed.
7. Sudden or Significant Changes in Bowel Habits
A sudden or significant shift in bowel habits, such as ongoing diarrhoea, constipation, or a marked change in stool appearance, may warrant medical attention. This is especially relevant when the change occurs alongside symptoms such as abdominal pain or bleeding.
Depending on the symptoms, a doctor may recommend a colonoscopy, which is a type of endoscopy that examines the large intestine. It can help identify conditions such as inflammation, polyps, or other abnormalities. During the procedure, the doctor may sometimes remove smaller polyps or collect tissue samples for further examination.
When Digestive Symptoms Need Attention
Digestive symptoms can have many possible causes, and experiencing one of these symptoms doesn’t always mean you’ll need an endoscopy. However, if symptoms are severe, recurring, worsening, or accompanied by other concerning changes, it’s important to speak with a healthcare professional for proper evaluation. They can determine whether an endoscopy or another diagnostic test is appropriate and recommend treatment based on the underlying cause.
Ultimately, endoscopy can be a useful tool for investigating digestive symptoms, identifying abnormalities, and, in some cases, providing treatment during the same procedure. With the right medical guidance, you can better understand what’s causing your symptoms and take the proper steps towards treatment.
