Symptoms
The symptoms of a rectal yeast infection may resemble those of a vaginal yeast infection, but they may also be more severe.
These types of yeast infections may be more common during pregnancy and are caused by the overgrowth of candida yeast.
Many other factors can influence the development of yeast infections.
Yeast are normally present in many areas of the human body. A yeast infection may develop when the levels of yeast become too high.
Immune System and pH levels
The immune system and some types of beneficial bacteria on the body normally keep the amounts of yeast under control, so that they do not cause any infections or damage to the body.
However, changes in the body’s pH levels, the amount of bacteria on the body, hormonal changes during pregnancy, and a weakened immune system can all contribute to yeast infections.
People with diabetes may be more susceptible because the disease can weaken the immune system as well, and elevated blood sugar levels may also encourage the overgrowth of yeast.
People with AIDS or HIV, as well as those on immune system suppressing medications, may also develop more frequent yeast infections and have more trouble getting rid of them.
Antibiotics can also encourage yeast infections by killing off some of the beneficial bacteria that normally keeps yeast levels under control.
Douching can also wash away the natural secretions and beneficial bacteria in and around the vagina, which can contribute to yeast infections.
Eating too much sugar and refined foods, such as white flour, may also encourage the overgrowth of yeast.
Factors such as tight or restrictive clothing can encourage yeast growth as well. Wet clothing, such as swimwear and exercise clothing, should not be worn for extended periods of time, and it should be washed before being put on again.
Sensitivities to soaps can also contribute to rectal and other yeast infections. It is best to avoid bubble baths and scented products like dyed and perfumed toilet paper, tampons, pads, and feminine hygiene sprays.
Pantyhose and other tight and synthetic clothing can create a warm, moist environment in which yeast can thrive. Loose fabrics and cotton underwear should be worn instead.
Rectal yeast infections cause a variety of symptoms, and some may not experience them all.
There may be redness, burning, and itching. There may also be discharge that can vary in color from white to yellow, and may have a yeastlike odor. The discharge will occur in the stool. Bowel movements may prove difficult.
Many types of antifungal creams and ointments are available over the counter. These can be useful for occasional yeast infections.
If they are overused for recurring yeast infections, the yeast may become resistant to the active ingredients, and they won’t work anymore.
In these cases, it is best to see a doctor. A doctor can also confirm the diagnosis, because some other types of infections may have similar symptoms but may not be caused by yeast.
A doctor can recommend alternative treatments or prescribe stronger medications, such as prescription oral antifungal drugs.
