Why Does Spicy Food Make You Hiccup? The Science Behind It

Spicy food is enjoyed by people all over the world. Whether it’s a plate of hot wings, a spicy curry, or a bowl of chili, the intense heat and flavor of these dishes can be incredibly satisfying. However, for some people, eating spicy food can also trigger an involuntary reflex – the hiccup.

Hiccups are a common and usually harmless reaction to eating spicy food, but have you ever wondered why this happens? In this article, we’ll explore the science behind the phenomenon and uncover the reasons why spicy food triggers hiccups.

What are Hiccups?

Before we delve into the reasons behind hiccups caused by spicy food, let’s first understand what hiccups are. Hiccups are an involuntary contraction of the diaphragm muscle, which is responsible for breathing. When the diaphragm contracts involuntarily, it causes the vocal cords to close suddenly, creating the familiar “hic” sound.

Hiccups can occur for a variety of reasons, including eating too quickly, drinking carbonated beverages, or consuming alcohol. In most cases, hiccups are harmless and go away on their own within a few minutes. However, in rare cases, hiccups can last for hours or even days, causing discomfort and disrupting daily activities.

Why Does Spicy Food Make You Hiccup?

Now that we understand what hiccups are let’s explore the reasons behind hiccups caused by spicy food. Scientists have proposed several theories, but they have not yet fully understood the exact cause of hiccups triggered by spicy food.

One theory suggests that capsaicin, the compound responsible for the heat in chili peppers, may stimulate the nerves in the esophagus and stomach, leading to hiccups. Another theory suggests that spicy food may cause the stomach to expand, putting pressure on the diaphragm, which can trigger hiccups.

Capsaicin and Nerve Stimulation

Chili peppers contain capsaicin, which gives food its spiciness and can cause a burning sensation on contact with sensitive tissues in the mouth, leading to tears, sweating, and hiccups. Capsaicin stimulates nerves in the mouth, throat, stomach, and esophagus, which can trigger the diaphragm to contract, causing hiccups. The esophagus can become irritated and inflamed, which can lead to hiccups.

Stomach Expansion

Another theory suggests that the expansion of the stomach after eating spicy food can lead to hiccups. When we eat, our stomach expands to accommodate the food.

However, when we eat spicy food, the expansion can be more significant due to the increased release of gastric acid and enzymes that are necessary to break down the spicy food. This expansion can put pressure on the diaphragm, which can cause it to contract involuntarily, leading to hiccups.

The Connection Between Hiccups and Spicy Food

Although we don’t fully understand the cause of hiccups triggered by spicy food, there is a clear connection between them. In a study published in the Journal of Neurogastroenterology and Motility, researchers found that capsaicin can induce hiccups in rats by stimulating the nerves in the esophagus and stomach.

While the study was conducted on rats, it suggests that a similar mechanism may be responsible for hiccups in humans.

Similarly, a study published in the Journal of Clinical Gastroenterology found that hiccups occurred more frequently in patients with gastroesophageal reflux disease (GERD) who consumed spicy food compared to those who did not.

GERD is a condition where stomach acid flows back into the esophagus, causing irritation and inflammation. The study suggests that the irritation caused by spicy food in patients with GERD may be responsible for triggering hiccups.

How to Prevent Hiccups Caused by Spicy Food:

While hiccups caused by spicy food are usually harmless and go away on their own within a few minutes, they can be uncomfortable and disruptive. Here are some tips to help prevent hiccups caused by spicy food:

  1. Eat slowly: Eating too quickly can lead to hiccups. Take your time and savor each bite of your spicy food.
  2. Drink water: Drinking water can help cool down the heat from the spicy food and may help prevent hiccups.
  3. Chew thoroughly: Chewing your food thoroughly can help prevent hiccups by reducing the amount of air you swallow.
  4. Avoid carbonated beverages: Carbonated beverages can lead to hiccups. Stick to still water or non-carbonated beverages.
  5. Take small bites: Taking small bites of your spicy food can help prevent hiccups by reducing the amount of stimulation on your esophagus and stomach.

The Benefits of Eating Spicy Food

While hiccups caused by spicy food can be uncomfortable, there are also several potential benefits to consuming spicy food. Here are a few ways that spicy food can be beneficial to your health:

Boosts Metabolism

Spicy food has been shown to boost metabolism, helping you burn more calories. Capsaicin, the compound responsible for the heat in spicy food, has been found to increase metabolic rate by up to 8%. This effect can last for several hours after consuming spicy food, making it an effective way to increase calorie burn.

Enhances Mood

Eating spicy food can also enhance your mood. Capsaicin has been shown to trigger the release of endorphins, the body’s natural painkillers. Endorphins can produce feelings of pleasure and euphoria, reducing stress and anxiety. Additionally, spicy food can activate the brain’s reward system, making you feel good and satisfied after eating.

May Improve Heart Health

Spicy food may also be beneficial for heart health. Capsaicin has been found to lower blood pressure by relaxing blood vessels and improving blood flow. This effect can reduce the risk of heart disease and stroke. Additionally, capsaicin has been shown to lower levels of LDL cholesterol, the “bad” cholesterol that can contribute to heart disease.

May Have Anti-Inflammatory Properties

Capsaicin has also been found to have anti-inflammatory properties. Inflammation is linked to a variety of health conditions, including arthritis, diabetes, and cancer. By reducing inflammation, capsaicin may help prevent or alleviate these conditions.

May Improve Digestion

Spicy food may also improve digestion. Capsaicin has been found to stimulate the production of digestive enzymes, which can improve digestion and nutrient absorption. Additionally, spicy food can increase gastric juice secretion, which can help break down food more efficiently.

Can eating spicy food cause permanent damage to the digestive system?

No, eating spicy food in moderation is not harmful to the digestive system. However, consuming extremely spicy food or overeating spicy food can cause discomfort and potentially lead to gastrointestinal issues.

Does drinking water help with the spiciness of food?

Drinking water can help alleviate the spiciness of food by diluting the capsaicin in the mouth. However, it’s important to note that water may not fully alleviate the spiciness and may only provide temporary relief.

Can eating spicy food cause ulcers?

No, spicy food does not cause ulcers. However, if you already have an ulcer, consuming spicy food can exacerbate the symptoms and make the condition worse.

Can spicy food help with weight loss?

Spicy food can aid in weight loss by boosting metabolism and increasing calorie burn. However, it’s important to note that consuming excessive amounts of spicy food or relying solely on spicy food for weight loss is not a healthy or sustainable approach.

Can spicy food cause heartburn?

Yes, consuming spicy food can cause heartburn in some people. This is because the capsaicin in spicy food can irritate the esophagus and cause acid reflux.

Can children eat spicy food?

Children can eat spicy food, but it’s important to introduce it gradually and in moderation. It’s also important to consider the child’s age and individual tolerance to spicy food.

Is there a difference in spiciness between different types of peppers?

Yes, different types of peppers have varying levels of capsaicin, which can affect the spiciness of the food. For example, a jalapeƱo pepper is generally milder than a habanero pepper.


Spicy food is enjoyed by many, but it can trigger hiccups for some. The cause is unclear, but it may be due to nerve stimulation or stomach expansion. While usually harmless, hiccups can be uncomfortable. Simple steps such as eating slowly, drinking water, chewing thoroughly, avoiding carbonated beverages, and taking small bites can prevent them.
