Persistent Loose Motions When Diarrhoea Needs Medical Attention

Almost everyone has had to deal with diarrhoea at one or the other point of time in their lives. The majority of such cases can be attributed to infections, changing lifestyle and dietary shifts, or due to some temporary disturbances in the stomach. The good news is that the loose motions get resolved with some rest and taking adequate fluids in a few days. But, when loose motions occur for weeks at a time and begin to interfere with your routine activities, you could be suffering from some digestive disorder.

Persistent loose motions can lead to dehydration, malnutrition and general discomfort. You will have to talk to a specialist at KIMS Sunshine Hospital right away!

What Causes Persistent Diarrhoea?

These are some common causes of persistent diarrhoea-

When there is a change in how the intestine works- it doesn’t absorb sufficient liquid from the food you consume or the digestive tract moves more rapidly to evacuate its contents; both of these conditions result in diarrhea.
Bacterial infections of the intestinal tract are an extremely common reason for severe or short-term bowel issues.
Persistent intestinal issues are sometimes the result of lasting intestinal attacks or, at times, from long-term medical conditions such as Irritable Bowel Syndrome. Sufferers who have suffered from IBS issues can experience variations in bowel routines, bloating and pain within the digestive tract.
Food intolerances and inflammatory bowel issues (IBD), cause frequent fluid bowel movements, as do malabsorption, insufficient digestion of foods and problems in the pancreas.
Even an excessive antibiotic course or stress could cause changes in digestive health, triggering enduring problems such as loose stools,

Symptoms of Persistent Loose Motions-

Diarrhea will, on its own, resolve at some point, but any diarrhea that lasts longer than two weeks is a reason to visit the doctor. Chronic diarrhea could, very slowly and gradually, cause someone to develop fatigue, weight loss, and nutrient deficiencies because there is poor absorption of vital vitamins and minerals.

The major complications caused by diarrhea can lead to dehydration, and it is characterized by symptoms of-

Drowsiness
Thirst,
Fatigue
Reduced urine output
Dry mouth.
Diarrhea with blood, high abdominal pain and fever and nighttime sleeplessness require doctor’s care.

Some have said that it starts after meals and others describe it as an urgent urge to pass stool multiple times throughout the day. Anyone who feels their condition impacts their social or work lives and their eating habits needs to seek medical advice. Seeing a specialist sooner rather than later if you develop diarrhea gives the opportunity to treat it early without further complications, and also helps identify the root cause of the issue.

How Chronic Diarrhoea Is Diagnosed and Treated?

To start, physicians try to understand how long the symptoms have been present, what has been eaten lately and what medicines have been used. Any complaints which are connected like abdominal pain and weight loss are also noted. Diagnostic tests used include-

Blood tests can reveal signs of inflammation, infection or malnutrition.
A stool test diarrhea diagnosis will be ordered in order to test for a bacterial, viral, or parasite type of infection. It can also be performed to see how well the digestive tract is functioning.
If they suspect you may have an issue with the gastrointestinal tract, such as IBD (inflammatory bowel disease), malabsorption disorders, or structural disorders, the doctor may have additional scans done or have an endoscopy or colonoscopy performed.

The underlying diagnosis determines the treatment. People with food intolerances can improve significantly by removing certain foods from their diet, while inflammatory conditions require management strategies for the long term. Several persistent diarrhea treatment options are available today and most patients improve considerably once the cause is determined and addressed accordingly.

Conclusion

Diarrhea should never be taken as a normal aspect of life, even if symptoms are, in general, very mild and intermittent. Digestive complications can potentially impact fluid intake, nutrient usage, and the quality of one’s everyday living over time.

Thus, being aware of your symptoms, ensuring satisfactory fluid intake, as well as getting a rapid health care evaluation in cases where persistent digestive complications continue, is a good preventive strategy that not just allows for the alleviation of disorders but is a safeguard against other future medical conditions.
