Why Are There Skid Marks in My Underwear?

Skid marks are the most common type of underwear stain and they may appear from a variety of causes… including diarrhea… flatulence… constipation… or poor diet. They are typically caused by watery stool entering the anus and traveling down the back of your legs.

This can happen when you aren’t wearing any underwear or when you haven’t changed your underwear for several days. They can also occur if you have recently removed a rectal suppository.

  • Skid marks are caused by friction that occurs between the body and the underwear. Friction happens when your underwear has been worn for too long without being changed. For example… if you wear the same pair of underwear for two days straight… it can cause skid marks.
  • The most common reason for skid marks is because you have diarrhea or loose stool. If you’re having trouble with constipation or diarrhea… then it can occur on a regular basis.
  • Skid marks are also caused when you become dehydrated and don’t drink enough water to keep yourself hydrated; this causes the inside of your body to dry out… and when your body dries out… it can cause skid marks to occur.

Other reasons why skid marks occur include:

  1. You’re pregnant.
  2. You have high blood pressure or cardiovascular disease.
  3. You have diabetes or poor blood circulation.
  4. You have irritable bowel syndrome or inflammatory bowel disease.
  5. Your diet doesn’t include enough fiber.
  6. You’re taking medicine such as diuretics or anti-anxiety medications that reduce your kidney function.
