Suffering from Dry mouth_
Suffering From Dry Mouth?

What is Dry mouth?

We all need saliva to moisten and cleanse our mouths and digest food. Our swallow can be hugely affected by how much saliva we produce. Saliva also prevents infection by controlling bacteria and fungi in the mouth. The condition in which the salivary glands in your mouth don’t produce enough saliva to keep your mouth moist is called dry mouth or Xerostomia.

What are the causes?

Side effects of certain medications

Almost all medications have some side effects, and the most common side effect of medication is dry mouth

It can be a common side effect of both prescription and non-prescription drugs, including drugs used to treat pain, depression, anxiety, allergies, and colds (antihistamines and decongestants), epilepsy, hypertension (diuretics), diarrhea, nausea, urinary incontinence, asthma (certain bronchodilators), and Parkinson’s disease and many more. It can also be a side effect of muscle relaxants and sedatives

Side effects of certain medical conditions

Dry mouth can be a side effect of medical conditions, including, Alzheimer’s disease, rheumatoid arthritis, hypertension, Parkinson’s disease, stroke, diabetes, anemia, cystic fibrosis, and mumps.

Side effects of certain medical treatments

Medical treatments – we would see a high prevalence of dry mouth with patients recovering from cancer treatments where the salivary glands have been affected by the treatment

Damage to the salivary glands through radiation or chemotherapy can reduce the amount of saliva produced.

Nerve damage

Dry mouth can be a result of nerve damage to the head and neck area from an injury or surgery.


Conditions that lead to dehydration, such as fever, excessive sweating, vomiting, diarrhoea, blood loss, and burns can also cause it.


Smoking or chewing tobacco substitutes, and vaping can affect how much saliva you make and aggravate dry mouth. Also breathing with your mouth open a lot can also contribute to the problem especially if there are nasal blockages and difficulty breathing through your nose.
