What is Esophageal Varices?
The esophagus tube runs in front of the spine and behind the windpipe and heart connecting the throat and the stomach. This tube is lined with a tissue called the mucosa. When the blood vessels around the esophagus become large or swollen it results in Esophageal Varices, EV. The larger these Varices are the more serious the condition becomes. When it is detected, the doctor grades it as per the size and is defined as the below types of Esophageal Varices.
Grade 1: Small
Grade 2: Enlarged
Grade 3: Large
Esophageal Varices Symptoms
There are no symptoms that are noticeable especially if the Varices are small. If it leads to variceal bleeding then a person will start to vomit blood in large quantities. Those who bleed in small quantities swallow the blood and their stools many become red. Varices caused due to cirrhosis will have liver disease symptoms. Some of the other signs seen when the Varices bleed include:
- Feeling continuously tired
- Feeling dizzy and faint
- Abnormally pale skin
- Vomiting red blood
- Tarry stools or red blood in stools
Immediate care of a gastroenterologist is needed if a person starts to see the above symptoms coupled with blood vomit.

- Enlargement of the Varices
- Portal hypertension which is an increase in the blood pressure in the portal vein
- Infection due to certain bacterias
- Red marks on the Varices
- Vomiting excessively due to other medical conditions

Esophageal Varices Causes
- The most common underlying cause of Esophageal Varices is cirrhosis which is scarring of the liver due to Hepatitis C. 30% of the people who have cirrhosis have Varices. Up to 5% of small Varices and 15% of the large Varices start to bleed in the first year of diagnosis.
- Portal hypertension is another cause for Varices. In this condition, the blood circulation to the liver is blocked. This results in a buildup of pressure in the portal vein. When the blood flow to the liver is restricted, it gets accumulated in the esophagus and causes swelling of the veins and becomes Varices.
- Budd-Chiari Syndrome and Schistosomiasis can also cause Varices.
How is Esophageal Varices diagnosed?
After inquiring about the symptoms and the medical history of the patients, the doctor will do a physical examination for Esophageal Varices diagnosis and order the below tests to confirm if it is EV.
- Blood tests: To check the counts of WBC, RBC, and Platelets. Kidney and liver function is also tested.
- Endoscopy: It is ordered to get a closer look at the veins and take tissue samples.
- Imaging tests: CT and MRI scans are ordered to evaluate the condition of the liver and the abdomen. The blood flow to the organs is also checked.
A person with cirrhosis should get tests done for EV regularly.
