A scratchy throat, also called an itchy throat, is a common condition that can involve an irritating sensation such as itching, scratching and soreness in the throat area. This sensation usually does not spread or develop into other conditions, but it can be quite uncomfortable and leave one feeling extremely irritable.

Scratchy throats can be triggered by a variety of factors, ranging from environmental irritants to underlying medical conditions. In this article, we’ll look at the causes, symptoms and treatments for the itchy throat, and the preventive measures one can take, and when it’s time to seek medical advice.

Prevalence

Itchy throat is a common symptom of allergies and affects people differently based on their age and gender.

In children and young adults, itchy throat and other unusual throat sensations are common. About 25.5% of students experience these symptoms, which often come with sore throat, stiff shoulders, and trouble sleeping.

Allergic rhinitis (AR), a condition that often causes an itchy throat, is more common in teenagers and adults. After puberty, women are more likely to experience AR due to hormonal changes and lifestyle factors.

Young people and women are more sensitive to irritants like carbon dioxide, which can cause throat irritation. Boys are more likely to be allergic to things like house dust mites during childhood, but in adulthood, women become more prone to these allergies.

Contact allergies, which can also cause throat irritation, are more common in adult women and increase with age. Overall, boys are more affected by food allergies causing itchy throat during childhood, while sensitivity to airborne allergens increases with age and becomes more common in women in adulthood.

Causes of Itchy Throat

Itchy throat can be triggered by several factors, including:

  • Environmental irritants: Exposure to smoke, dust, chemical fumes, or other pollutants can irritate the throat and cause itchiness.
  • Allergies: Allergies to certain seasons or specific substances, such as pollen or pet dander, can also cause an itchy throat.
  • Dry air: low humidity, especially in indoor conditions with central heating or air-conditioning.
  • Viral infections: These include common colds, flu and other viral infections. These can irritate and itch the throat.
  • Acid reflux: When stomach acid has back flowed from the gastroesophageal sphincter into the oesophagus, it has to be classified as a throat irritant and an itch-producer.
  • Certain medicines: Some medicines, including ACE inhibitors taken to control blood pressure, cause a dry, scratchy cough.

Symptoms of Itchy Throat

Alongside the ‘scratchy’ or ‘itchy’ feeling in the throat, symptoms may include the following:

  • Dry cough
  • Hoarseness or changes in voice
  • Sore throat
  • Difficulty swallowing
  • Postnasal drip (mucus drainage from the sinuses down the back of the throat)



Remedies and Treatments for Itchy Throat

Here are some home remedies and over-the-counter treatments for an itchy throat:

  • Throat hydration: If possible, drinking plenty of water or warm liquids, like herbal tea with honey, can help soothe and moisten the throat.
  • Humidity: Using a humidifier or taking a steamy shower can add moisture to the air so you don’t have to deal with dry and itchy throats.
  • Saltwater gargle: Mix 1/2 teaspoon salt in a cup of warm water and gargle away. This can help cut down on inflammation, alleviating those itchy throat sensations.
  • Lozenges can help moisten your throat by stimulating saliva.
  • Cough: cough suppressants might help with a dry cough that could result from irritation While over-the-counter medications can provide you with some relief, it is best to consult your physician about the remedies and not self-medicate. Medicines such as cough suppressants and antihistamines could help provide you with some relief. If you must take medication, remember to drink plenty of water.
  • An itchy throat due to acid reflux could be treated with generic antacids or prescription medications to reduce stomach acid production.

Preventing Itchy Throat

To help prevent itchy throat, consider the following measures:

  • Minimise exposure to smoke, dust and other irritants: Avoid environmental irritants as much as possible – these include exposure to smoke, dust, fumes or pollutants.
  • Palliate allergies: Avoid substances that trigger itchy throat symptoms (many allergy sufferers find it useful to identify and steer clear of their specific allergens) and use over the counter or prescription allergy drugs if necessary.
  • Keep indoor humidity: Run a humidifier in very dry season or in a room with air-conditioning.
  • Keep clean: Wash your hands regularly and stay away from people with colds or flu to avoid getting viruses that can make your throat itch.
  • Treat acid reflux: Avoid foods and beverages that trigger acid reflux, including spicy or fatty foods, caffeine, and alcohol. Eat small, frequent meals and avoid lying down after meals.

When to See a Doctor for an Itchy Throat?

While an itchy throat is often a minor irritation that can be cured with home remedies and over-the-counter medicine, it’s important to consult a medical doctor under certain circumstances:

  • Itchy throat symptoms that persist for 2 days despite home treatment
  • Severe sore throat or difficulty swallowing
  • High fever (over 38.4°C) accompanied by itchy throat
  • Swelling in the face, tongue, or throat
  • Difficulty breathing or wheezing
  • Itchy throat accompanied by a rash or hives

These symptoms may be indicators of a more serious underlying problem, like a bacterial infection or serious allergic reaction, that needs immediate evaluation and treatment by a medical professional.

FAQs

The duration of itching in the throat may be different depending on the cause. For example, cases that are produced through environmental irritants or dry air should heal within a few days, but for other conditions that are produced through allergies or viral infections may last longer.

Lots of throat medications, from home remedies to drugs that require a prescription, have no immediate treatments that relieve an itchy throat. There are no pills that you can take to immediately feel better if you currently have throat itching. As with most medical ailments, it is a syndrome of environmental factors. However, you can help to ease symptoms (and identify the source) by drinking plenty of water, using a humidifier, gargling with saltwater, or taking over-the-counter drugs such as ibuprofen .Try to identify and manage any allergies and treat other underlying conditions such as acid reflux.

Yes, your itchy throat could be an allergy symptom, possibly related to seasonal allergies (‘hay fever’) and/or to specific allergens (particular indoor or outdoor irritants such as pollen, animal dander or certain foods). If your itchy throat is paired with symptoms common in allergies, such as sneezing, runny nose, or itchy eyes, it might be caused by allergies.

If your throat gets itchy when you are exposed to some particular man-made environmental irritants, for example, smoke, dust, or fumes and when you are away from these irritants your symptoms improve, most likely your symptoms are caused by environmental exposures. Patterns and symptom diaries, then, are invaluable tools to help you figure out environmental triggers.
