Why Do Cold Sores Come Back?

· January 7, 2016
The virus usually becomes active and appears when triggered by certain things. For some, the virus remains inactive and does not manifest.

Many people have the tendency to suffer from recurring illnesses which affect organs that are already weakened by genetics, bad habits, nutritional deficiencies, etc. One of the most common cases is cold sores, which is more a problem of appearance than a serious threat to your health.

In this article, we’ll explain why those who have cold sores usually suffer from them every so often and how you can deal with them naturally.

What are cold sores?

Cold sores are a small ulceration or blister that appears around the lip as a result of herpes virus simplex 1 (HSV-1). Although they are more common in the areas around the lips, they can form on any part of the body.

They usually begin with a slight tingling or itching and after a little while, they turn into a blister causing more itching and even pain.

Why do they come back?

There are a few people who only experience the symptoms of this virus once in their lives. However, it’s more common for cold sores to appear from time to time because the virus remains in the body.

In general, the HSV-1 virus is contracted in childhood and is spread by contact. It enters the body through the skin and permanently locates itself in the nerve cells.

When certain triggers happen, the virus is activated and a cold sore appears on the lip. Other people who have it may not experience symptoms as the virus can stay inactive or dormant.


The exact cause that triggers the virus is not known. However, some factors can assist in activating the virus:

  • Stress: Stress causes imbalances in the body and attacks the body’s natural defenses. In the majority of cases, an outbreak doesn’t occur during times of stress, but just after, when the body is relaxing and trying to restore its natural rhythms.
  • Infections and fevers causes by other pathogens, including those in other parts of the body.
  • Medication: Taking certain medications, especially antibiotics, can weaken the immune system and activate the herpes virus.
  • Hormonal changes: The most common are those associated with menstruation or pregnancy.
  • Extreme weather: Exposure to solar radiation or extreme, sudden changes in temperature can increases the chances of a cold sore developing.
  • Food allergies/intolerances: Sometimes the body doesn’t digest certain foods well, like gluten, lactose, soy, certain fruits, etc. These types of cases can be difficult to detect because the reaction is not always immediate.
  • Intestinal disorders: According to some researchers, cold sores may a sign of inflammation or ulcers in parts of the intestinal wall.
