Breath smell, also known as halitosis, is a common issue in dental health as I studied, and it can be attributed to issues related to oral hygiene like gum disease or tooth decay. However consistent changes in breath smell can also be a sign of more serious health conditions, such as pancreatic cancer. By recognising the connection between breath smell and systemic disease, dental professionals can improve patient awareness and early detection.
Causes of bad breath
- The smell is persistent and unpleasant – Bad breath is the most obvious symptom is a consistently unpleasant smell coming from the mouth. It is possible for others to observe this smell or for one to detect it themselves using a breath test.
- Dry mouth – Bad breath can become worse with a dry mouth. Lack of saliva can result in the buildup of smell-causing compounds, which are essential for washing away food particles and bacteria.
- Metallic or sour taste – Bad breath can often accompany a metallic or sour taste in the mouth, which can indicate bacteria or other underlying issues.
- White coating on the tongue – Bacteria and food particles can be found on the tongue, leading to bad breath due to a white or yellowish coating.
- Gum disease symptom – This is often linked to bad breath, which can be accompanied by symptoms such as swelling, bleeding gums and receding gum lines.
- Tooth decay or abscesses – If you have cavities or dental abscesses, decaying food particles or infection can lead to foul-smelling breath.
- Sore throat or post-nasal drip – Conditions like sore throat, post-nasal drip or sinus infections can contribute to bad breath as mucus drains into the throat.
- Difficulty eating or swallowing – Infections or severe dental issues can cause problems with eating or swallowing, which can lead to bad breath.
What is Pancreatic cancer?
Pancreatic cancer is a cancer that develops in the pancreas, which is an organ that plays a significant role in digestion and blood sugar regulation. It is challenging to treat cancer that often grows silently and is diagnosed at an advanced stage. Bad breath is a potential symptom of pancreatic cancer.
- Digestive issues – The pancreas can have tumours that block the bile duct or digestive tract, resulting in digestive problems that can lead to foul-smelling breath.
- Metabolic changes – The body can produce ketones due to metabolic changes caused by advanced pancreatic cancer, particularly if there is significant weight loss or poor nutrient absorption. The breath can have a distinct smell due to these ketones, which are often described as fruity or acetone-like.
- Bad breath can be caused by pancreatic cancer, which can be caused by infection or complications.
- Unexpected weight loss
- Nausea and vomiting
- Fatigue
- Diabetes
- Loss of appetite
- Jaundice – Yellowing of the skin and eyes, often accompanied by dark urine and light-coloured stools.
When should I visit a dentist?
In case you or someone you know experiences persistent bad breath, unusual changes in your mouth and other symptoms as I mentioned before it’s important to get a thorough evaluation from a healthcare professional.
