Why Does My Eyes Water When I Eat?


Tearing or watering of the eyes while eating is a common phenomenon that can be caused by a variety of factors. While this may be a temporary and benign issue for some individuals, excessive tearing while eating can be a sign of an underlying medical condition that requires treatment. Understanding the causes of tearing while eating can help individuals identify and address any underlying issues.

Causes of tearing while eating:

  1. Spicy foods: One of the most common causes of tearing while eating is the consumption of spicy foods. Spicy foods contain compounds known as capsaicinoids, which stimulate the pain receptors in the mouth and throat and can cause the eyes to tear as a reflex response. This is a normal and temporary response to spicy foods and is not typically a cause for concern.
  2. Allergies: Allergic reactions can also cause tearing while eating. Allergies to certain foods or food additives, such as preservatives or dyes, can cause symptoms such as watery eyes, runny nose, and sneezing. Allergic reactions can also be triggered by environmental allergens, such as pollen or dust, which can cause similar symptoms.
  3. Dry eye: Dry eye is a condition in which the eyes do not produce enough tears or the tears evaporate too quickly, leading to dryness and discomfort. Dry eye can be caused by a variety of factors, including medications, medical conditions, and environmental factors such as dry air or prolonged computer use. Dry eye can cause tearing while eating, as the act of chewing can stimulate the production of tears and cause an overflow.
  4. Blepharitis: Blepharitis is an inflammation of the eyelids that can cause symptoms such as redness, itching, and watering of the eyes. Blepharitis can be caused by a variety of factors, including bacteria, irritation, or allergies, and it can be treated with medications or changes to the individual’s skincare routine.

Treatment and prevention:

The treatment for tearing while eating will depend on the underlying cause. For individuals with dry eye, treatment may involve the use of artificial tears, warm compresses, or changes to the environment or lifestyle to increase tear production. For those with allergies or blepharitis, treatment may involve medications, such as antihistamines or antibiotics, or changes to the individual’s skincare routine. In most cases, avoiding spicy foods or allergens can help prevent tearing while eating.


Tearing while eating can be caused by a variety of factors, including spicy foods, allergies, dry eye, and blepharitis. Identifying and addressing the underlying cause of tearing can help individuals find relief and prevent further discomfort. Working with a healthcare provider can help individuals determine the cause of their tearing and develop a treatment plan that addresses their specific needs.
