Black mold in toilet bowl diabetes

Black mold in toilet bowl & diabetes

The big question here is “Could be having black mold in the toilet regularly be a sign of diabetes?”

Are you finding mold in your toilet more and more often? Although you might just be frustrated with having to clean it up, there’s a chance it’s also a clue you should get your blood sugar checked.

As strange as it sounds, frequently seeing black mold in your toilet could be a sign you have diabetes, but let’s find out more about that in this article.

What is a mold?

Mold is a type of fungi that grows and thrives in damp environments. In nature, molds work to break down plant and animal matter. They can also be found indoors.

You’ll often see them in areas exposed to higher levels of moisture, such as bathrooms and kitchens. In fact, you’ve probably come across a ring of mold in your toilet at one time or another.

Whether it’s black mold or orange mold, they’re both hazardous to the human body’s overall functioning. Black mold, on the other hand, has the ability to spread harmful compounds such as venom.

What is black mold, exactly?

It is self-evident that it is one of the numerous mold types, but there is more to it. Technically, black molds are known as stachybotrys chartrum.

The dangerous fungus can form on any surface that has been exposed to too much moisture, and it has a green and black appearance.

Black molds, surprisingly, do not spare toilet bowls, which is a matter of concern for all of us. After all, toilet bowls are used by multiple people numerous times every day. Furthermore, it is thought that black mold in the toilet bowl and diabetes are linked in some way.

There’s a theory that frequent black mold in your toilet could be a sign of diabetes. This is because the urine of someone who has diabetes can contain high levels of sugar that the mold uses as food.

Mold is an organism that can thrive in any environment but prefers organic substances. Organic substances containing glucose (often known as sugar) are particularly attractive.

When a person’s diabetes is uncontrolled or inadequately controlled, the body’s reduced ability to digest glucose is compensated for by “dumping” glucose through urine and sweat. Mold spores thrive in the presence of that glucose-rich fluid, which feeds them.

Mold can grow in practically any damp, rarely cleaned, or badly cleaned environment. As a result, mold in the toilet should be removed and the bowl sanitized (of course), with further investigation into the cause as needed, although the existence of the organism is no proof of any medical problem.

Can Black Mold in the Toilet Indicate Diabetes?

Mold and diabetes are connected, according to a study conducted by Doug A. Kaufman. First and foremost, it is critical to understand that mold does not cause or worsen diabetes. The relationship is actually the polar opposite.

There have been no scientific studies that relate the presence of toilet black mold to diabetes. However, a chronic accumulation of black mold in your toilet could indicate that you or someone in your household has diabetes that is undiagnosed or poorly treated.

Below is why

Diabetic glycosuria

Diabetes patients’ urine may include high quantities of sugar (glucose). This is referred to as glycosuria. When glucose levels in a urine sample exceed 25 mg/dl, an individual is considered to have too much glucose in their urine.

Sugar is normally reabsorbed by the kidneys and returned to the circulation. However, not all of it can be reabsorbed since persons with diabetes have high blood sugar levels. The excess sugar is excreted in the urine.

When blood sugar levels are 180 mg/dl or above, extra sugars are often seen in the urine. Diabetes is diagnosed when blood sugar levels are 126 mg/dl or higher and 200 mg/dl or higher, respectively, on a fasting or random plasma glucose test.

Glycosuria can also make you urinate more frequently. Because the increased sugar in the urine might attract more water, the bladder will fill up faster.

Mold and glycosuria

Mold can grow in places where there is a lot of moisture, such as the toilet bowl. Sugars such as glucose can also be used as a food source.

Molds in a toilet may utilize this sugar as food since people with diabetes can have glycosuria. Furthermore, because patients with diabetes may urinate frequently, mold may be exposed to these sugars more frequently.

Molds are thought to grow and thrive in an environment where these characteristics are present. As a result, people with untreated or poorly managed diabetes are more likely to detect mold rings in their toilets.

Keep in mind that there have been no scientific studies linking toilet mold with diabetes to date. Toilet mold is frequently caused by environmental causes that have nothing to do with your health.

What Causes Black Mold in the Toilet Bowl?

Aside from diabetes, mold growth in toilets is caused by a variety of factors including moisture, leaks, and cracked tiles. Molds in toilets are regularly found in toilet bowls, and here are all of the reasons why.

Not flushing properly, delays, and omissions in flushing the toilet result in the growth of bacteria and, eventually, black mold.

You may have noticed unpleasant scents and strange items on various surfaces, including the toilet bowl. This is because the toilet bowl is not thoroughly cleaned during this period, allowing mold to thrive.

Hardness in water is known to cause havoc. It affects not only your health but also the surfaces that are exposed to it. Because water is used frequently in toilet bowls, it frequently results in mold growth.

How to Remove Black Mold from a Toilet Bowl

Diabetes and black patches in the toilet bowl are connected. However, you can simply eliminate these black spots at home by utilizing a variety of approaches.

To get rid of mold in toilets, you can use alcohol, vinegar, or a chlorine bleach solution. Keep in mind that using bleach can be challenging because bleach has a strong nature and can leave stains and degrade the surface’s appearance.

Also, for the best results, dilute each of the ingredients with water. Otherwise, rather than solving the problem, it may exacerbate it.

When eradicating molds, remember to wear goggles, a mask, and gloves because the fungus is more damaging to your health than a single glass of carbonated beverage.

How to Prevent Black Mold in Toilet Bowl?

Whether or not the toilet is used by diabetic patients, make sure to flush and bleach it on a regular basis. Regular cleaning will keep bacteria and, eventually, black molds from taking over the room.

Repair any leaks around the toilet seat right away. Also, if the flush is broken, fix it because only a properly functioning flush can completely remove the toxins.

Plants and rugs should not be placed near the toilet seat because they encourage the growth of black mold. If you can’t part with your rugs, wash them on a regular basis and bring them in when they’re entirely dry.

Because moisture is the major source of energy for molds, make sure your bathroom has a good ventilation system to let the moisture out easily.

Frequently asked questions (FAQs)

Is mold harmful to your health?

Molds are generally harmless to humans. Mold can cause health concerns in certain people, especially when it reaches high levels. Among the signs and symptoms are:

  • headaches
  • red or itchy eyes
  • stuffy nose
  • sneezing
  • wheezing
  • skin rash

What is the significance of a black ring?

Mold comes in many different colors, including green, white, and black.

When people talk of hazardous mold, they usually mean Stachybotrys atra. This mold is dark green or black in appearance. It could appear slimy or tarry. This is unlikely to be the type of mold in your toilet, though. This is because it only develops on certain materials, including wood, paper, and ceiling tiles.

What does it mean to wear a pink ring?

The presence of a pink ring in your toilet is rather common. While mold can generate a pink ring in your toilet, it can also be caused by a bacteria called Serratia marcescens. These bacteria grow in moist settings and produce a pink, orange, or red tint.

A pink toilet ring could also be created by iron in the water as a result of aged pipes. If this is the case, it is likely that all of your toilets will be affected.


Is it possible that black mold in the toilet bowl is a sign of diabetes? Yes, it is a possible indicator. This is because mold that grows in toilets can feed on additional sugar found in diabetics’ urine.

There is currently no scientific evidence linking mold in the toilet to diabetes. Mold development might be aided by the toilet’s surroundings. Poor ventilation, as well as infrequent cleaning or flushing, can all contribute.
