We sometimes feel a little uncomfortable about the smell coming from our mouth. It's normal. It can happen when you eat spicy foods like onions or garlic, or when you don't brush your teeth properly. However, if your breath smells fruity, like nail polish remover, then it's not normal. This could be a sign of a serious health problem. That's what we're talking about today.
Why does my breath smell like acetone?
Simply put, if your breath smells like this, it means that your blood levels of chemicals called ketones are high. Don't be afraid of the word "ketones." Let's keep it simple.
Our body's cells need energy to function. This energy comes from the sugar called glucose in the food we eat. It's like gasoline for a car. However, if for some reason our cells can't use this glucose, the body finds another alternative. That is to burn the fat stored in the body to produce energy .
Think of it like trying to run a car with something like kerosene when it runs out of gas. The car runs, but it's not good for the engine and it smokes. Similarly, when the body burns fat, these acids called ketones are added to the blood as a byproduct. When these ketone levels get too high, your breath starts to smell like acetone or fruit.
What is the relationship between diabetes and acetone breath?
This condition called acetone breath is mainly associated with diabetes mellitus, especially in people with type 1 diabetes .
Diabetes is a condition in which the level of glucose (sugar) in the blood rises above the normal level. Normally, the hormone insulin, produced by our pancreas, acts like a key that unlocks the door to allow glucose into our cells. In a person with diabetes, the body produces less or no insulin at all. Or, the body cannot use the insulin it produces properly.
So, what happens when you don't have insulin? Glucose can't get into the cells. It just builds up in the blood. But the cells don't have energy. It's like locking the kitchen door when the house is full of food , and the family has to go hungry.
This is when the body starts burning fat for energy, as mentioned earlier. Then the level of ketones in the blood increases dangerously. We call this condition Diabetic Ketoacidosis (DKA) . This is a very serious, life-threatening medical emergency.
One of the main and earliest signs of DKA is this fruity smelling breath. This is one of the first signs that doctors look for when they suspect DKA.
What are other symptoms of DKA?
In addition to acetone breath, there are several other symptoms of DKA. These can appear very quickly, sometimes within 24 hours. They may be among the first symptoms that someone newly diagnosed with diabetes experiences.
| Symptom | What does this mean? |
|---|---|
| Intense thirst and frequent urination | The body tries to excrete excess sugar in the blood through the kidneys in the urine. At the same time, a large amount of water is also excreted from the body, causing intense thirst. |
| Nausea and vomiting | Elevated levels of ketones in the blood can cause stomach upset, nausea, and vomiting. |
| Fatigue and weakness | The body feels extremely tired and weak because the cells do not receive the energy (glucose) they need. |
| Difficulty breathing | When the acidity of the blood (due to ketones) increases, the body tries to control it by breathing faster and exhaling carbon dioxide. |
| Confusion | This condition affects brain function, which can lead to decreased alertness and confusion. |
| Sudden weight loss | Because the body burns fat for energy, weight loss can occur rapidly (especially in newly diagnosed type 1 diabetes). |
When should you seek immediate medical advice?
This is a very important part.
- If you are diabetic and your breath smells like acetone, first of all, follow the treatment plan your doctor has given you exactly. That means taking insulin injections and medications on time.
- If you are following treatment correctly, but your ketone levels (measured with test strips) are moderate or high, call your doctor immediately.
- Even if you don't have diabetes, if you have any concerns about this persistent acetone smell, definitely see a doctor.
DKA is a medical emergency. If you have one or more of the following symptoms, go to a hospital's emergency department (ETU) immediately.
* If you have more than one of the DKA symptoms mentioned above.
* If you cannot contact your doctor.
* If your blood sugar level is consistently higher than 300 mg/dL.
Please do not take this situation lightly. Prompt treatment can save a life.
Are there other causes of acetone breath besides diabetes?
Yes. Although diabetes is the main cause, this condition can also occur due to several other reasons.
| Reason | Description |
|---|---|
| Keto Diet and Fasting | The keto diet is a high-fat, moderate-protein, and very low-carb diet. It forces the body to burn fat for energy. This also happens when you fast for long periods of time. This can cause ketone levels in the blood to rise, which can cause a fruity smell on your breath. |
| Alcoholic Ketoacidosis | Ketones can also become dangerously high in the blood of people who drink a lot of alcohol, who don't eat properly, and who vomit. This is also a very serious condition. Symptoms like vomiting and stomach pain can be confused with other medical conditions. But prompt treatment is essential. |
