Anti diarrhea medicine

We occasionally experience diarrhea and wonder if any anti-diarrhea medicine can be taken to relieve pain. Many drugs can help relieve diarrhea, but we need to know certain types and their benefits and side effects before taking them. The dosage is also to be known, which is suitable for a particular individual. There are also natural remedies that help get rid of diarrhea, but first, let’s understand what exactly diarrhea is.

Diarrhea, in most cases, occurs when the large and small intestines cannot absorb ions and water, so one experiences watery stool. Diarrhea can be mild to severe, depending on the person’s condition. Mild diarrhea mostly lasts from 1 day to 14 days, while severe diarrhea may last for more than four weeks. Most people feel better within a day or four days after taking an anti-diarrhea medicine.

The anti-diarrhea medicine, also called antidiarrheals, is used to cure acute and chronic diarrhea. Antidiarrheals help to reduce the frequency of stool passing but will stop working once the effect of the medications is over, so the underlying cause should be treated to get permanent relief from diarrhea, as the anti-diarrhea medicines give only temporary relief. So, let’s look at some of the common causes of diarrhea.

3. Loperamide or Imodium

Loperamide or Imodium, in most cases, is prescribed for acute diarrhea and diarrhea associated with inflammation of bowel movements. Loperamide (Imodium) is also given to people with ileostomies to reduce fluid in a person’s body. Loperamide (Imodium) reduces fluids secretion which helps to stop the loose stools immediately as the body absorbs the liquids. Loperamide is helpful to slow diarrhea but should not be used for constipation as it may worsen.

Loperamide or Imodium helps to solidify the poop, thus reducing the symptoms of diarrhea. Loperamide is known for being a drug that cannot be controlled, which causes many severe reactions which would affect the body negatively. So, seeking a doctor’s permission immediately is advised to minimize the impact and improve your medical conditions significantly if you notice any severe side effects.

Having diarrhea can cause dehydration, so maintaining the body’s fluids is very difficult as the body does not absorb the water. So no treatment has any effects, so one is given electrolyte drinks.

So, if you feel dehydrated or have diarrhea, drinking plenty but electrolyte drinks like ORS, coconut water, smoothies, or fruit juices is recommended. The ORS is mainly taken with water; more water helps to recover quickly. But you should not exceed the consumption of electrolytes as it affects bodily fluids, blood, tissues, and urine.

The food is starchy and has low fiber, which helps the digestion process easy.

Along with the BRAT diet, it is advisable to have other bland foods like baked or boiled potatoes, crackers, broth, weak tea, apple juice, or cooked cereals. The patients are suggested to give rest to intestines to reduce the intestinal contractions and eat food that helps to improve gut health.
