Urine has a sweet smell_Why does urine have a sweet smell

The sweet taste of urine is caused by high blood sugar. Because the sugar is not fully absorbed by the human body and is excreted, it has a great impact on the urethra. It is hoped that patients with high blood sugar should avoid eating sweets and foods with relatively high sweetness. In addition to being a symptom of high blood sugar, sweet smelling urine may also be caused by the patient consuming too much sweets on that day and the body not fully absorbing them.

The appearance and odor of urine can be affected by diet and fluid intake. If the smell of your urine changes temporarily, it may be due to something you have eaten recently. For example, asparagus can make your urine have an unusually strong smell. Additionally, some medical conditions, medications, and supplements can affect the smell of your urine. The most common causes of sweet-smelling urine include:

diabetes

Patients with poorly controlled diabetes will have excess glucose excreted in the urine due to high blood sugar levels. Therefore, urine smells sweet. Patients may experience fatigue, thirst, changes in appetite, and unexplained weight loss.

Diabetic ketoacidosis

Diabetic ketoacidosis (DKA) is an acute, severe, life-threatening complication of diabetes that occurs primarily in patients with type 1 diabetes but can also occur in some patients with type 2 diabetes. DKA is characterized by hyperglycemia, ketosis and acidosis. It is a severe metabolic syndrome caused by the combined effects of insufficient insulin and excessive insulin-antagonizing hormones. DKA is the most common acute complication of diabetes and requires emergency treatment. In addition to the sweet smell of urine, these patients may also have rotten apple smell on their breath (acetone smell), confusion, epileptic seizures, etc.

Maple Syrup Urine Disease

This disease is an autosomal recessive genetic disease, named because the urine of the affected child has a special maple syrup smell. It mainly invades the nervous system, often manifesting symptoms of progressive brain damage, and is an important cause of mental retardation in children. In severe cases, convulsions, paralysis or severe metabolic disorders may occur. Children often experience decerebrate spastic paralysis, convulsions and coma, with shallow breathing and intermittent cyanosis; urine has a maple syrup smell; some children may also have hypoglycemia, ketoacidosis, and a full anterior fontanelle. Such people should follow a strict diet and have regular blood tests or take long-term medications to prevent liver failure.

Certain medicines and supplements

Some supplements, especially vitamin B6, can change the smell of urine. Certain medications can also affect the look and smell of urine.

Dehydration

When the body is dehydrated, the urine becomes more concentrated and may turn yellow or even brown. The more concentrated the urine, the stronger the odor. While the most common odor is a pungent ammonia smell, some patients report that the urine smells sweet or fruity.

Yeast infection

Yeast is a fungus that usually causes vaginal infections in women, but can also occur in men. A yeast infection itself won't affect the smell of your urine, but it can cause your vaginal discharge to have a sweet smell. Symptoms of yeast infection include: vulvar itching and burning pain, which may also be accompanied by frequent urination, painful urination and painful sexual intercourse, and the secretions are like bean curd.

To sum up, when the urine has an abnormal odor but there are no other symptoms, it is generally necessary to observe for a day or two. However, you should see a doctor immediately if you experience any of the following symptoms: thirst; abdominal pain or nausea; severe pain in the back, abdomen, or genitals; fever; tiredness; or blood in the urine.
