Diabetes affects every little bit of your life. But could it even be affecting your toilets? Diabetes discussion forums are filled with people commenting on mold in their toilets. Some claim it didn’t start until diagnosis, some say it only happens in the bathrooms someone with diabetes uses, and some say they only see it when their blood sugars aren’t well controlled.

Diabetes and toilet mold

Many users on the Diabetic Connect discussion board have made claims like this one from Im0nGuard: “I was having black-colored mold in my toilets within three days of cleaning them before I was diagnosed. Once I was diagnosed and got my blood sugar down to a near normal range, the mold problem went away. I was guessing after the fact that it was from all the sugar in my urine.” This discussion had 60 responses. Some people shared similar experiences, while others claimed it was impossible for diabetes to cause toilet mold.

The problem has been cropping up in other forums too. On TuDiabetes, user KayceeWersal made a similar comment saying, “I know this may seem weird but since being diagnosed I have noticed that my toilet has started to grow black mold. I clean and within a few days more has formed. I will admit my sugars aren’t the lowest. Average is maybe 300. Is there a connection, and anyone else have this problem?”

There seems to be plenty of anecdotal evidence, but what about researched facts?

What causes toilet mold?

That mold you might see in your toilet is a fungus that thrives in moist, warm places like your bathroom and specifically your toilet. Even if you spend time cleaning your bathroom the best you can, mold and mildew can still grow and build up in your toilet bowl creating a black waterline.

Amanda Mott blogging at Mold Blogger suggests, "If the body is overwhelmed by glucose, it will attempt to flush as much of the excess out of its system by means of sweat, exhalation, and urination. It is quite plausible that the mold found in your clothing or in your toilet bowl is a sign that your body is truly suffering from an abundance of glucose and needs help."

While our online search found no scientific researched relationship between diabetes and toilet mold, it doesn’t mean it’s impossible. Keep cleaning and know you are in the company of many others who suspect this problem.

Preventive measures

Be sure you are cleaning your bathroom regularly, and check your toilet tank to be sure it’s clean as well. Try using an antifungal spray in your bathroom at least once a month. If you live in a humid or wet area, try placing a dehumidifier in your home to discourage mold growth. If you notice your toilet bowl seems cleaner when your blood sugars are well controlled, great!
