About this video
Did you know that your body smell can reveal hidden health problems?
Unusual odors in breath, sweat, or urine are often signals from your body about an underlying medical issue. In this video, we will discuss different types of smells, their causes, and the diseases linked with them.
1️⃣ Sour Smell → Stomach Acid Reflux
When stomach acid frequently moves up into the esophagus, it causes acid reflux. This condition can produce a sour smell in the mouth because of the regurgitated acid mixed with partially digested food. Chronic acid reflux can also cause bad breath, heartburn, and indigestion.
2️⃣ Fruity Smell → Diabetes (Ketoacidosis)
A fruity or sweet smell in breath is a warning sign of uncontrolled diabetes. This happens when the body starts burning fat for energy instead of glucose, producing ketones. High ketone levels in the blood and urine lead to a fruity odor, often linked to a dangerous condition called diabetic ketoacidosis (DKA).
3️⃣ Ammonia Smell → Kidney Disease
If your breath, sweat, or urine smells like ammonia, it could be related to kidney disease. Damaged kidneys cannot properly filter waste products, leading to the buildup of urea and toxins in the body. When urea breaks down, it releases an ammonia-like odor.
4️⃣ Fishy Smell → Bacterial Vaginosis
A fishy vaginal odor is most commonly associated with bacterial vaginosis (BV). This condition occurs when harmful bacteria overgrow and upset the natural vaginal flora. It may also be linked with itching, discharge, or discomfort.
5️⃣ Sulfur / Rotten Eggs Smell → Gut Issues
If your burps or breath smell like rotten eggs or sulfur, it is often related to gut problems. Conditions like gas, indigestion, food intolerance, or infections can cause hydrogen sulfide gas, which smells like rotten eggs. Poor gut health and unhealthy diet also contribute.
6️⃣ Metallic Taste / Smell → Liver Disease
A metallic taste or odor in the mouth can be a sign of liver disease. When the liver fails to filter toxins, chemicals like sulfur compounds build up in the blood and create a metallic or musty smell, sometimes referred to as fetor hepaticus.
👉 Always remember: Persistent unusual smells should never be ignored. They may indicate a serious health condition that needs medical attention.
