Hypersalivation
What is Hypersalivation?
Hypersalivation is a condition where your body produces too much saliva. Most people make about 1 to 2 liters of saliva each day. With hypersalivation, your salivary glands work overtime and create more than your body needs.
This excess saliva can pool in your mouth or cause drooling. Some people also call this condition sialorrhea or ptyalism. It can happen suddenly or develop slowly over time. The condition itself is not a disease but a symptom of an underlying issue.
Hypersalivation affects your quality of life in many ways. You may feel embarrassed about drooling or need to spit frequently. The constant wetness can irritate your lips and skin. Understanding the root cause helps you find the right treatment approach.
Symptoms
- Excessive drooling or spitting
- Difficulty swallowing or managing saliva
- Constant need to wipe your mouth
- Skin irritation around the mouth and chin
- Chapped or cracked lips
- Changes in taste or metallic taste in mouth
- Bad breath despite good oral hygiene
- Speech difficulties due to excess saliva
- Choking or gagging sensation
- Dehydration from losing too much saliva
Some people may not notice mild hypersalivation at first. Symptoms often become more obvious when eating or talking. The severity varies based on the underlying cause.

Causes and risk factors
Hypersalivation happens when something triggers your salivary glands to overproduce or when you cannot swallow saliva normally. Mercury toxicity is one important cause that affects both salivary gland function and your autonomic nervous system. Other causes include certain medications, pregnancy, infections, neurological conditions, and gastroesophageal reflux disease. Pesticide exposure and other heavy metal poisoning can also trigger excessive saliva production.
Risk factors include working in industries with heavy metal exposure like mining or manufacturing. Taking certain medications for mental health conditions or Parkinson disease increases your risk. Dental problems, poorly fitted dentures, and mouth infections can stimulate extra saliva. Some people experience temporary hypersalivation during pregnancy or when trying new medications.
How it's diagnosed
Doctors diagnose hypersalivation by reviewing your symptoms and medical history. They will examine your mouth, teeth, and throat to rule out local causes. Blood tests help identify underlying issues like heavy metal toxicity that may be causing excessive saliva production.
Rite Aid offers mercury testing as an add-on to our health panel. This blood test measures mercury levels to confirm if metal toxicity is causing your symptoms. Testing at Quest Diagnostics locations makes it easy to check for environmental exposures. Early detection helps you address the root cause before symptoms worsen.
Treatment options
- Remove exposure to mercury and other heavy metals if identified
- Work with a doctor on chelation therapy for confirmed heavy metal poisoning
- Adjust medications that may be causing excess saliva
- Use anticholinergic medications to reduce saliva production
- Try botulinum toxin injections into salivary glands for severe cases
- Practice good oral hygiene to prevent secondary infections
- Use barrier creams to protect skin around your mouth
- Stay hydrated and maintain a balanced diet
- Consider speech therapy to improve swallowing coordination
- Explore surgical options for glands if other treatments fail

Frequently asked questions
Excessive saliva can result from many causes including mercury toxicity, medications, infections, and neurological conditions. Your salivary glands may overproduce or you may have trouble swallowing normally. Heavy metal exposure from work or environment is an often overlooked cause. Blood testing helps identify toxicity as a root cause.
Hypersalivation itself is not life threatening but it signals an underlying problem that needs attention. The excess saliva can lead to choking, skin infections, and social embarrassment. If caused by heavy metal toxicity, the underlying poisoning can damage your nervous system and organs. Early diagnosis and treatment prevent serious complications.
Mercury toxicity often causes hypersalivation along with other symptoms like tremors, mood changes, and metallic taste. A blood mercury test confirms if toxic levels are present in your body. People with occupational exposure or who eat large amounts of certain fish are at higher risk. Testing helps rule mercury in or out as a cause.
Some cases of hypersalivation resolve when the trigger is removed, like stopping a medication or treating an infection. Mercury related hypersalivation requires active treatment to remove the metal from your body. Without addressing the root cause, symptoms usually persist or worsen. Work with a doctor to identify and treat the underlying issue.
Antipsychotic medications, some antidepressants, and drugs for Parkinson disease commonly cause hypersalivation. Seizure medications and certain antibiotics can also trigger excess saliva. If you suspect your medication is the cause, talk to your doctor about alternatives. Never stop taking prescribed medications without medical guidance.
Treatment for mercury poisoning starts with eliminating further exposure to the metal. Chelation therapy uses special medications that bind to mercury and help your body remove it. The process can take weeks to months depending on severity. Supporting your liver and kidney function helps your body detoxify more effectively.
While diet alone cannot cure hypersalivation, certain foods may help or worsen symptoms. Avoiding extremely sour or acidic foods may reduce saliva stimulation. Eating foods rich in antioxidants supports your body if toxicity is the cause. Stay well hydrated since excessive spitting can lead to fluid loss.
See a doctor if you have persistent drooling, difficulty swallowing, or other concerning symptoms. Seek immediate care if you have trouble breathing or severe choking episodes. If you work with heavy metals or have known exposure, get tested even with mild symptoms. Early intervention prevents complications and addresses root causes.
Blood mercury testing is very accurate for detecting recent or ongoing exposure to the metal. Blood levels reflect what is currently circulating in your body. For chronic or past exposure, hair or urine tests may provide additional information. Blood testing is the first step in confirming mercury as a cause of symptoms.
Chronic hypersalivation can lead to skin breakdown around your mouth from constant moisture. You may develop fungal or bacterial infections in affected areas. Difficulty managing saliva increases choking and aspiration risk. The underlying cause, especially heavy metal toxicity, poses greater health risks than the excess saliva itself.
