Itchy throat can arise in a variety of situations such as allergies, exposure to irritants, infections or other situations that are usually easy to treat.
In addition to the scratching throat sensation, coughing is also very common, which in most cases is a defense of the body to this irritative stimulus, but other symptoms such as swelling in the throat or runny nose, for example.
The most common causes usually include:
Dehydration occurs when there is an insufficient amount of water in your body due to factors such as insufficient fluid intake, diarrhea, vomiting, heat stroke or excessive sweating. Dehydration may be accompanied by symptoms such as itchy throat, thirst, dry mouth, dry skin and eyes, decreased urine and blood pressure, and in more severe cases, increased heart rate and dizziness.
What to do: The treatment consists of ingesting isotonic drinks and oral rehydration solutions bought from pharmacies, or making a homemade saline solution at home by mixing 1 tablespoon of sugar and 1 teaspoon of salt in a liter of water and after it cools down, you should drink it throughout the day. In addition, water-rich foods such as watermelon, orange or pineapple may also be eaten.
2. Allergic rhinitis
Allergic rhinitis is an inflammation of the nose mucosa, triggered by an allergic reaction, leading to symptoms such as sneezing, runny nose, dry cough, and itchy nose and throat. This disease usually arises after contact with allergic substances such as dust, pet hair, pollen or some plants and is therefore more frequent during the spring or autumn.
What to do: Allergic rhinitis is not curable, but it can be treated with antihistamines such as loratadine, cetirizine or desloratadine for example, as well as nasal rinsing and you should try to avoid the substances that are causing the allergies.
3. Food allergy
A food allergy is an exaggerated inflammatory reaction to a specific substance present in food and can manifest in different body regions such as the skin, eyes, nose or throat. In addition, swelling may also occur in various regions of the body, which may reach the mouth, eyelids and tongue and can cause severe breathing difficulties.
A drug allergy is very similar to a food allergy, however it is easier to identify the allergen, as the allergic reaction occurs shortly after taking the specific drug.
What to do: Treatment consists of the administration of antihistamines such as loratadine or cetirizine, or corticosteroids such as prednisolone, but in case of a severe reaction, it may not be enough and so urgency should be taken immediately because the allergy may develop into an anaphylactic shock.
It is also very important to have a food allergy test to avoid the foods that cause the problem.
4. Exposure to irritants
Exposure to irritants such as tobacco smoke or car exhaust pipes, cleaning agents and other toxic or irritating substances may irritate the throat and may also cause itching and coughing.
What to do: Avoiding exposure to irritants that cause itchy throat sensation is the most effective measure. However, if this is not possible, you can use calming pills that have honey, lemon or ginger in their composition, or gargle with water and salt solutions.
5. Tonsillitis or a cold
Some respiratory infections such as tonsillitis, pharyngitis, or a cold can make your throat itch before it develops into more severe symptoms, such as pain or inflammation in the area. Symptoms may also include runny nose, cough, fever, itchy ear, chills and discomfort.
What to do: Treatment depends on the type of infection, and usually, if it is bacterial tonsillitis or pharyngitis your doctor may prescribe antibiotics such as amoxicillin, erythromycin or penicillin, pain killers and anti-inflammatory drugs to relieve pain and inflammation such as acetaminophen and ibuprofen. If it is flu or a viral pharyngitis, it is important to treat the symptoms such as inflammation, pain and fever with painkillers, anti-inflammatory and antipyretic drugs such as acetaminophen, ibuprofen, aspirin or novalgine.
In addition, it may also be necessary to use dry cough medication such as Dropropizine or phlegm coughs like Mucosolvan and antihistamines to alleviate allergic symptoms such as desloratadine or cetirizine.
6. Gastroesophageal reflux
Gastroesophageal reflux is the return of the stomach contents to the esophagus towards the mouth, causing pain, unpleasant taste and in some cases itchy throat due to irritation caused by your stomach acid content. This happens when the muscle that should prevent stomach acid from escaping from the stomach does not work properly.
What to do: Treatment for reflux consists of taking antacids that neutralize stomach acid, prevent burning in the esophagus, or prokinetics, which accelerate gastric emptying, therefore reducing the time that food stays in the stomach.
7. Drug side effects
Some medication can cause itchy throat as a side effect and should not be confused with an allergic reaction, which is very common in people taking ACE inhibitors, which are medication to help lower blood pressure.
What to do: Usually this side effect usually subsides over time, but if it persists and causes a lot of discomfort, you may need to replace the medication. In addition, taking a spoonful of honey, gargling with salted water, or having a tea with ginger and lemon can alleviate the itchy throat sensation.
