We've probably all been on either end of the digestive spectrum: unable to go No. 2 or having it all flow out. Diarrhea and constipation are very common conditions for people of all ages.

These digestive issues can last a day or two – but sometimes they last longer. Here's some information on causes of diarrhea and constipation and tips to clear up irregular bowel movements.

What are the symptoms of diarrhea?

Diarrhea means having loose or liquid stool. For most people, diarrhea is mild and goes away within a day or two. However, other times it can be a sign of a more serious condition. It can cause dehydration and may prevent your body from holding onto nutrients.

Aside from watery stool, other symptoms of diarrhea include:

  • Bloating or cramping in your stomach
  • Strong and urgent need to poop
  • Upset stomach or nausea

With severe cases of diarrhea, you may also have other symptoms. These could be signs of a serious medical issue:

  • Fever
  • Severe pain
  • Vomiting
  • Blood or mucus in your stool

If you have these other symptoms or symptoms of dehydration, contact your health care provider.

Are there different types of diarrhea?

There are three types of diarrhea:

  • Acute diarrhea: This is the most common type of diarrhea. It usually lasts a couple days or less and gets better without treatment.
  • Persistent diarrhea: This type usually lasts a couple weeks to a month.
  • Chronic diarrhea: This can last a couple months or comes and goes over and over. It could be a sign of a serious condition.

Your stool may also be a different color than normal. The color of your stool may be connected to what you're eating.

  • Yellow diarrhea: If it's more yellow than brown, it could mean that you have too much fat in your diet. Your body may not be digesting food properly. Yellow stools could also mean that you have celiac disease. This is where your body isn't able to process gluten, which is in many breads, pastas and pastries.
  • Green diarrhea: Greenish stool can be normal and isn't usually cause for concern. Green diarrhea could be a sign that the food moved too quickly through your body. It could be from eating green foods, such as kale, spinach or even drinks with green food coloring.

What conditions may cause diarrhea?

Diarrhea is often caused by a virus in your gut (stomach area). Some people call it the stomach flu. It can also have many other causes, including:

  • Eating foods that upset your digestive system
  • Bacterial infection (such as food poisoning) or other organisms
  • Allergies to certain foods
  • Taking too much laxative
  • Reaction to certain medications like antibiotics or cancer drugs
  • Diseases of the intestines, such inflammatory bowel disease, including Crohn's disease or ulcerative colitis
  • Some cancers
  • Surgery on your digestive system
  • Trouble absorbing certain nutrients
  • Overactive thyroid, known as hyperthyroidism

When should you seek treatment for diarrhea?

You should see a health care provider if you have the following symptoms:

  • Fever above 101° F that lasts more than 24 hours
  • Severe pain in your stomach or rectum
  • Nausea or vomiting that prevents you from drinking liquids
  • Diarrhea after returning from a foreign country

Are there at-home treatments for diarrhea?

If you have diarrhea, you can use at-home remedies to help get rid of it.

  • Drink plenty of fluids, such as water, drinks with electrolytes, tea, and even nonfat chicken broth. Avoid caffeine and alcohol as these can dehydrate you more.
  • Eat the BRAT diet, which includes bananas, (white) rice, applesauce and toast. These foods help firm up your stool. 
  • Avoid foods that can cause gas, such as beans, brussels sprouts and carbonated drinks. You should also avoid dairy because diarrhea can make you temporarily lactose intolerant.
