Bad Taste In Back Of Throat: Causes And Treatment

Dry Mouth

Dry mouth occurs when there’s insufficient saliva to keep the mouth moist. This can happen due to dehydration, smoking, certain medications, or medical conditions affecting the salivary glands. Without enough saliva, food particles and bacteria buildup. This leads to bad breath and an unpleasant taste.

Acid Reflux (GERD)

Acid reflux or gastroesophageal reflux disease (GERD) involves stomach acid traveling back into the esophagus, often causing a sour taste in the mouth. Other symptoms include heartburn, bad breath, nausea, sore throat, cough, and hoarseness. 

Oral Thrush

Oral thrush is a fungal infection. It causes a bad taste and a cottony sensation in the mouth. You may notice white sores on the tongue or inner cheeks. Cracking at the corners of the mouth is common. Other symptoms include loss of taste, difficulty eating or swallowing, and pain or irritation under dentures.

Respiratory Infections

If you have experienced a bad tasting phlegm in back of throat, it’s likely a respiratory infection. Sinusitis, tonsillitis, colds, and other respiratory illnesses can contribute to a bad taste. These conditions often include a sore throat, headache, and nasal or sinus congestion. A runny nose, earache, and fever may also occur. 

Nutritional Deficiencies

Your taste and oral health can be affected if your body lacks vitamins and minerals, such as vitamin B12, zinc, vitamin C, and folate. Sadly, this can lead to an unpleasant taste. 

By knowing these common causes, you can better manage and mitigate the discomfort of a bad taste in back of throat.

Uncommon Causes Of A Bad Taste In Back Of Throat

While the common causes of an unpleasant taste in the back of the throat are well-known, several lesser-known factors can also contribute to this discomfort.

• Medications. Certain drugs can alter taste perception. These include antibiotics, ACE inhibitors, oral contraceptives, antirheumatic drugs, immunomodulating drugs, antidepressants, antiseizure drugs, antipsychotic drugs, and opioids. Adjusting the dosage or switching to other options may help.
• Pregnancy. Hormonal changes during pregnancy can impact taste and smell, often resulting in a metallic taste. This typically improves as the pregnancy progresses. 
• Serious health conditions. Hepatitis and chronic kidney disease can also cause undesirable taste. Neurological conditions like brain injuries, tumors, dementia, epilepsy, and diabetes can also be causes. They affect saliva production and taste.

If the issue persists, seek medical advice. A healthcare provider will assess the patient’s medical history and symptoms. They may carry out tests to pinpoint the underlying cause.
