What food allergies cause post nasal drip

Stomach pain is the primary symptom of a food allergy. It typically starts soon after eating. Other symptoms include bloating, constipation and diarrhea. Some foods such as milk can cause nasal congestion or post-nasal drip. Food allergies can also cause tongue swelling, throat itch, rashes, hives or even anaphylactic shock.

What are the treatment options for a food allergy?

There’s no cure, pill or magic treatment for a food allergy. The best practices involve either decreasing the allergen in the diet or eliminating it altogether.

If someone has numerous food allergies, we might propose a rotation diet where you still eat the allergic foods, but you rotate how often you eat them and make certain you are not eating multiple allergens in one day.

Another option might be an anti-histamine diet, which involves avoiding foods that produce histamine.

Nightshade plants, which include tomatoes and eggplant, are histamine producers and can make allergic symptoms worse.

I also recommend a 21-day elimination diet to law out foods that trigger an allergic response. This involves taking one food out of the diet for 21 days to see if you feel better. If you notice an improvement, that food likely contributed to your food allergy.

In rare cases, some providers might give you little amounts of the allergen over a prescribed quantity of time. There is some evidence to propose this could be helpful in overcoming an allergy.

Laryngopharyngeal Reflux (LPR)

What is LPR?

LPR is similar to Gastroesophageal Reflux Disease, or GERD.

It occurs when the lower esophageal sphincter (LED) does not shut properly and the stomach contents are allowed to leak back or reflux into the esophagus and then up to the voice box and possibly the back of the nose and sinus cavity. When the refluxed stomach acid comes into contact with the lining of the esophagus, it causes a burning sensation in the chest or in the throat that we call heartburn or acid indigestion. When stomach contents irritate the voice box and back of the throat/nose, symptoms are less often heartburn, and more often consist of post nasal drip, throat clearing, cough, and lump in the throat.

What are the symptoms of LPR/GERD?

The classic symptom of GERD is heartburn.

Numerous people own LPR without any associated heartburn and instead they experience chest pain, hoarseness, difficulty swallowing, excessive mucous, throat clearing, a sensation of a lump in the throat, sore throat, choking spells, wheezing, post-nasal drip, dry cough, or bad breath.


Your doctor may also recommend medications that you can purchase over the counter or may give you a prescription for a medication. These medications can assist to neutralize the acid in your stomach, stop acid production, or assist the muscles that empty your stomach. Medications work in diverse ways and a combination of medications may assist to best control your symptoms.

Your doctor is the best source of information on how to use these medications.

What causes LPR?

Eating habits, diet, and obesity every contribute to the development of GERD. Eating large meals and lying below after eating may induce reflux symptoms. Numerous foods are acidic or contain irritating substances that increase the stomach’s production of acid.

Obesity and pregnancy also contribute to LPR/GERD symptoms because the additional weight places increased pressure on the sphincter muscles in attempt to hold food in the stomach. Tight fitting clothing may put pressure inside the abdominal cavity much love excessive body weight does and therefore may cause reflux symptoms.

What is the treatment for LPR/GERD?

Lifestyle Changes: 

  1. Avoid foods that are acidic or contain irritating substances that increase the stomach’s production of acid. Foods that are known to promote reflux include: fatty foods, spicy foods, coffee, tea, soda, and other caffeinated beverages, alcohol, chocolates, nuts, citrus fruits and juices, mints, cough drops, breath fresheners, gum, hard candies, and some mouthwashes.
  2. Multiple little meals spread throughout the day is preferable to fewer larger meals.

    Less food in the stomach at a time will lead to less reflux.

  3. Try not to eat anything for 3 hours before bedtime because reflux is often worse when we lie down.
  4. Weight loss often results in significant reduction of reflux symptoms. Avoid tight fitting clothing.

Raising the head of your bed may also assist to counteract the loss of gravity that occurs from lying down.

How do you diagnose LPR/GERD?

LPR/GERD may be diagnosed by carefully listening to the symptoms the patient reports along with a thorough examination of the head and neck.

There are also a number of diagnostic tests available to assist establish and monitor a diagnosis of LPR/GERD: 

  1. pH monitoring: A little tube is put into the esophagus that will stay there for 24 hours. While you go about your normal activities, it measures when and how much acid refluxes into your esophagus. Manometry can also be performed using the same probe.

    This detects pressure changes and is a more sensitive technique than measuring pH alone.

  2. Barium swallow: You drink a solution and then several x-rays are taken to assist spot abnormalities such as a hiatal hernia or narrowing of the esophagus.
  3. Upper endoscopy: The doctor will spray your throat to numb it and then slide below a thin, flexible tube called an endoscope. A tiny camera in the endoscope allows the doctor to see the esophagus and to glance for abnormalities.
  4. Nasal endoscopy: Numerous ENT doctors will apply a topical nasal decongestant and numbing medicine to the lining of the nose by a nasal spray prior to endoscopy.

    Often, the examination can be completed without any special medicines at every. A rigid or flexible scope may be used to see around corners — much love a child’s toy periscope. Nasal endoscopy provides a detailed examination of the nasal cavity, sinuses, and voice box.

What is Causing Your Post Nasal Drip?

What food allergies cause post nasal drip

Many conditions can cause postnasal drip. Allergies are one of the most common. Dr. Bublik can test for allergies and law out if this is the cause of this annoying symptom.

Another common cause could be a deviated septum; this means the cartilage between your nostrils or septum leans to one side or is displaced. In some cases, the crooked septum can interfere with the drainage of the sinuses causing postnasal drip or resulting in repeated sinus infections.

What is happening when you own an allergic reaction to food?

An allergic reaction to food is your body’s way of saying there is an invader in the body, so it’s time to fight it.

The body triggers an immune response to the food, and it typically causes inflammation in the gastro-intestinal tract.

Can a prebiotic and probiotic assist ease food allergies and sensitivities?

Patients will start a probiotic thinking it will make their gut issues better. Research shows it might assist in some cases, but the extent to which it helps is not clear. It certainly won’t be harmful to take probiotics, and there is some evidence they can be more beneficial for children than adults. I own parents who tell me if they miss giving their kid the probiotic, gut pain and bloating returns.

It’s not going to hurt you if you take a probiotic, and there is potential it can lead to more calmness in the gut. But there’s still a lot of research needed.

 Glands in the nose and throat normally produce 1-2 quarts of mucus every day. This mucus moistens the lining of the nose and sinuses, humidifies the air, traps inhaled particles, and helps to fight infections. Normally this mucus is swallowed unconsciously numerous times throughout the day. When the mucus becomes thick or excessive in volume, it can cause the sensation of post-nasal drip.

Post-nasal drainage can often lead to cough, sore throat, frequent throat clearing, and the feeling of a lump in the throat.

An excess in thin, clear secretions can be from viral infections, allergies, spicy foods, temperature changes, pregnancy and some medications (birth control pills, blood pressure medications). Increased thick secretions can happen from low humidity in the winter, a decrease in fluid intake (dehydration), bacterial sinus infections, or from some medications (antihistamines). Swallowing problems or acid reflux can give patients similar symptoms of nasal/throat drainage or phlegm.

A correct diagnosis of the underlying problem is essential to properly treat a patient with post-nasal drip.

Treatments for viral infections, allergies, and sinusitis are discussed in other sections.

Acid reflux is treated with over-the-counter or prescription medications, depending upon the severity of the symptoms. Other causes are less common and should be thoroughly evaluated by an ENT specialist.
