Diabetic pee often smells sweet or fruity, like honey, popcorn, or even maple syrup, because the body tries to get rid of excess sugar (glucose) through urine, especially with uncontrolled blood sugar. In serious cases, like Diabetic Ketoacidosis (DKA), it can smell strongly fruity due to ketones, requiring immediate medical help, say experts from Mayo Clinic and WebMD. This symptom, combined with increased thirst, frequent urination, and tiredness, warrants a doctor's visit.
A person with uncontrolled diabetes may have high blood glucose levels. The body tries to get rid of the extra glucose through urine, which can cause it to have a sweet smell, similar to honey. People with sweet-smelling urine due to diabetes may notice other symptoms, including: exhaustion.
Foul-smelling urine may be due to bacteria. Sweet-smelling urine may be a sign of uncontrolled diabetes or a rare disease of metabolism. Liver disease and certain metabolic disorders may cause musty-smelling urine.
It's normal to have a small amount of sugar in your pee. But if urine (pee) test results show more than 0.25 mg/ml of glucose, that's glycosuria. Sometimes, glycosuria is a symptom of hyperglycemia (high blood sugar). But it can also happen in people with normal or low blood sugar levels.
One sign that you possibly have diabetes or high blood sugar is urine that smells sweet or fruity. The sweetness comes from sugar in your urine and is a sign your body is trying to get rid of extra sugar in your blood.
Kidney failure can make urine smell strongly of ammonia or have a fishy odor, often due to built-up waste products (amines) or infection, signaling concentrated urine from dehydration or kidney dysfunction. Other signs alongside bad-smelling urine include foamy, bloody, or cola-colored urine, swelling, fatigue, and changes in urination, all pointing to potential kidney issues that require a doctor's evaluation.
The 2 main symptoms of diabetes insipidus are often needing to pee a large amount of urine and feeling extremely thirsty. If you have diabetes insipidus, you may pee pale, watery urine every 15 to 20 minutes. The amount of urine can range from 3 litres in mild cases to up to 20 litres per day in severe cases.
Symptoms of hyperglycaemia
Frequent urination, especially if it disrupts your sleep at night, coupled with excessive thirst, can be indicative of your body struggling to manage blood sugar levels effectively. These symptoms are often subtle at first but can become more noticeable as prediabetes progresses towards type 2 diabetes.
The health care provider uses a dipstick made with a color-sensitive pad. The color of the dipstick changes to tells the provider the level of glucose in your urine. If needed, your provider may ask you to collect your urine at home over 24 hours . Your provider will tell you how to do this.
You should worry about urine smell and see a doctor if it's persistent, accompanied by fever, pain/burning during urination, cloudy or bloody urine, or if it smells sweet (potential diabetes) or rotten (potential infection/kidney stones). While often temporary due to dehydration or food, persistent strong or unusual odors, especially with other symptoms, warrant medical attention to rule out UTIs, diabetes, or other conditions.
If you are dehydrated, your urine may smell like ammonia. Maple syrup urine disease. This genetic disease can cause the amino acids leucine, isoleucine and valine to build up in the blood. People with this condition may have urine that smells like maple syrup.
Patients affected by trimethylaminuria will often have fishy-smelling urine. Trimethylaminuria is a genetic disorder in which affected individuals have an enzymatic deficiency that makes them unable to metabolize TMA. Because they cannot metabolize TMA, affected individuals have a buildup of TMA in their bodies.
The excess sugar and ketones make their way into your urine, resulting in that tell-tale popcorn smell. Uncontrolled diabetes can lead to ketoacidosis, a life-threatening metabolic state that occurs when you have excess ketones in your blood.
Three common signs of diabetes are increased thirst and frequent urination, extreme tiredness, and blurry vision or slow-healing sores, often stemming from high blood sugar levels affecting the body. These symptoms, sometimes called the "Three Ps" (polyuria, polydipsia, polyphagia), can develop slowly in Type 2 diabetes or quickly in Type 1.
If you have more glucose than normal in your urine, it could mean that you have: Too much glucose in your blood, which could be a sign of diabetes. Diabetes is the most common cause of high urine glucose levels.
Five early signs of diabetes include frequent urination, increased thirst and hunger, fatigue, blurry vision, and slow-healing sores or frequent infections, stemming from high blood sugar levels that affect the body's ability to use glucose for energy, leading to these common symptoms.
Feeling very thirsty. Feeling very hungry—even though you are eating. Extreme fatigue. Blurry vision.
Drink more water
“Water helps your kidneys filter out excess sugar through urine,” says Khan. “So, the more hydrated you are, the more urine production you'll have, which flushes out sugar in the body.” Always opt for water instead of sugary drinks, like soda and juice.
A normal HbA1c is generally below 5.7% for all adults, but levels naturally tend to rise slightly with age, with upper limits increasing for older adults (e.g., around 6.0-6.5% for those 60+) to avoid hypoglycemia, though specific targets depend on individual health, with 5.7-6.4% indicating prediabetes and 6.5% or higher suggesting diabetes.
Classic signs and symptoms that suggest you've moved from prediabetes to type 2 diabetes include:
If you urinate often, and your pee is very light-colored or even clear, it could be a sign of diabetes. However, it can also be a sign that you are over-hydrating yourself. But remember: Excessive thirst is often a warning sign of diabetes, which will cause you to drink more water.
The worst foods for diabetics include:
Foul-smelling pee can be a sign of a bacterial infection, such as a urinary tract infection. Musty-smelling urine can indicate liver disease or certain metabolic disorders.
If your kidneys aren't working properly, you may notice one or more of the following signs:
