Why Do I Taste Blood in My Throat? - Common Causes and What to Do

Feeling a metallic, bitter taste in your throat can be alarming. This article explores the common causes of tasting blood in the throat and provides guidance on what you should do if you experience this sensation.

Introduction

Occasionally, one might experience a metallic taste in the throat, often mistaken for tasting blood. While benign causes such as bites to the mouth or minor throat irritation are common, it is important to be aware of potential serious underlying issues. This guide will help you identify the probable causes and when you should seek medical attention.

Common Causes of Tasting Blood in the Throat

Biting into a Vein or Artery

The most likely cause of tasting blood in the throat is biting into a vein or artery. This can happen when you accidentally bite the inside of your mouth, causing a small injury or tearing of blood vessels. It's particularly common to bite the inside of your mouth without realizing it when you're distracted or eating quickly.

Biting into a nerve can cause significant pain and, in rare cases, even lead to temporary paralysis if the nerve is damaged severely. This is more common if you bite hard or if there is a pre-existing condition in the mouth that makes the nerves exposed more.

Throat Injuries

Another possible cause is a raw or sore throat, which can result from scraping the throat while eating. This can happen if you have a cut or abrasion on the throat from accidentally biting the back of your tongue or cheek, or from ingesting rough or sharp food.

Nasal Traces

At times, blood from the nose can also make its way into the throat. This can happen due to nosebleeds or sinus issues. Even tiny amounts of blood can give a metallic taste. If there is an ongoing nosebleed or blood in the mucus, it can be a more significant issue requiring medical attention.

Non-Severe Causes

It is important to note that many times the metallic taste in the throat is not due to any serious medical condition. Temporary cases of sore throat, cuts, or abrasions usually clear up on their own within a few days. However, if the taste continues for more than a week, it is advisable to consult a healthcare provider.

When to Seek Medical Attention

Severe or Persistent Symptoms

If the taste in your throat persists for more than a week, if it is accompanied by severe pain, or if you experience other symptoms like swelling, difficulty swallowing, or fever, it is advised to seek medical attention.

Additionally, if you have been diagnosed with or suspect you might have conditions like internal bleeding, COVID-19, a severe upper respiratory infection, or inflamed tonsils, it is important to address these issues promptly.

Inspection by a Healthcare Professional

Have someone use a flashlight to inspect your mouth and check for any visible wounds or signs of trauma. If you cannot see anything, it is time to make an appointment with a doctor or clinic for a more thorough examination. A healthcare professional can determine the cause of the taste and recommend appropriate treatment.

Conclusion

While tasting blood in the throat can be concerning, it is often not a cause for panic. Most of the time, it is due to benign causes like a bite to the mouth or a minor throat injury. However, persistent symptoms or other accompanying issues should prompt a visit to a medical professional.
