Diabetes can cause urine to appear dark yellow, amber, or even tea-colored due to high glucose levels and dehydration, often with a sweet or fruity smell, and sometimes appear cloudy from excess sugar or infections; while pale/clear urine can signal good hydration or diabetes insipidus, persistent changes warrant a doctor's visit.
Typically, diabetic urine may appear more yellow or amber-colored due to increased glucose concentration ((Raymond and Yarger, 1988) and (Aycock and Kass, 2012)). As dehydration increases, which is common in poorly controlled diabetes, urine becomes darker and more pronouncedly yellow ((Belasco et al., 2020)).
Common Urine Color Changes in Diabetic Patients
Dark yellow or amber-colored urine can mean your urine is too concentrated, often from not drinking enough water. Cloudy or turbid urine might mean you have a urinary tract infection. Urine that looks red or cola-colored could have blood in it.
Cola- or tea-colored urine or urine that smells can be a sign of kidney disease. Orange-hued urine can be a sign of problems with your liver or bile duct. Greenish or cloudy pee can be a sign of a UTI. Dark brown pee or pee that smells like ammonia can be a sign of liver failure.
Diabetes: People with diabetes often have too much sugar (glucose) in their blood. To get rid of the extra glucose, the body moves it from the blood into the urine. So, when someone has undiagnosed or untreated diabetes, they tend to pee more often. And their urine looks clear.
Symptoms of hyperglycaemia
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.
Healthy urine is clear (not cloudy), odorless and in a shade of yellow that can range from very pale to a darker, amber-like hue. “The shade of your urine depends on your hydration level,” explains Dr. Leong. “The gold standard, so to speak, is to achieve a pale yellow color the shade of diluted apple juice.
An unusual urine color also can be a sign of a health problem. For instance, some urinary tract infections can turn urine milky white. Kidney stones, some cancers and other diseases sometimes make urine look red due to 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.
But it can also happen at night. When there's too much sugar in your blood, which happens if you have diabetes, your kidneys have to work harder to get rid of it. This forces them to make more urine. The process doesn't stop just because you're snoozing.
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.
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.
A urine glucose test can tell you whether there is glucose (sugar) in the urine, and gives an indication of the glucose level. If glucose is found in your urine it is called glycosuria or glucosuria. Glucose is usually only found in the urine when blood glucose levels are raised due to diabetes.
If you urinate often, and your pee is very light-colored or even clear, it could be a sign of diabetes.
But as this autoimmune disease progresses, dark urine may occur. In fact, healthcare providers consider orange or dark-colored urine to be a common symptom of liver damage. This is due to a substance called bilirubin being present in your urine.
The most optimal color for your urine is a pale yellow. If it is a darker yellow or orange, it can mean you are becoming dehydrated.
If your urine is persistently red or pink (and not from food), dark brown or cola-colored, orange with pale stools or jaundiced skin, cloudy, foamy, foul-smelling, green, purple, blue, or black, it's worth checking in.
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.
Three key early warning signs of kidney problems are changes in urination (more or less frequent, especially at night), foamy or bloody urine, and persistent swelling, particularly around the eyes, feet, or ankles, indicating fluid retention. Other common signs include persistent fatigue, nausea, itching, and loss of appetite, as toxins build up when kidneys aren't filtering effectively.
A popcorn smell or sweet-smelling urine is often an early indicator of untreated or undiagnosed diabetes. Diabetes affects your blood sugar levels and causes high ketone levels. The excess sugar and ketones make their way into your urine, resulting in that tell-tale popcorn smell.
A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes. Glucose tolerance test.
