Dry mouth, choking sensation. What is this?

I am 55, and not in the best physical condition of my life. In the past few weeks I have tried to exercise, doing some treadmill work. I notice that with some exertion, I start to experience dry mouth, but worse, a chokiing sensation. I realize I am breathing through my mouth, but I ve done that before with no problem. I do not feel physically exhausted, nor even particularly fatigued when this happens, but the choking sensation is preventing me from pushing myself further.

There are several causes of dry mouth, also called xerostomia.

These include :-

Side effect of certain medications: Dry mouth is a common side effect of many prescription and nonprescription drugs, including drugs used to treat depression, anxiety, pain, allergies, and colds .

Side effect of certain diseases and infections: Dry mouth can be a side effect of medical conditions, including Sjögren's syndrome, HIV/AIDS, Alzheimer's disease, diabetes, anemia, cystic fibrosis, rheumatoid arthritis, hypertension, Parkinson's disease, stroke, and mumps.

Side effect of certain medical treatments.:Damage to the salivary glands, the glands that produce saliva, for example, from radiation to the head and neck and chemotherapy treatments for cancer, 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.

Dehydration: Conditions that lead to dehydration, such as fever, excessive sweating, vomiting, diarrhea, blood loss, and burns can cause dry mouth.

Surgical removal of the salivary glands.

Lifestyle. Smoking or chewing tobacco can affect saliva production and aggravate dry mouth. Continuously breathing with your mouth open can also contribute to the problem.

Steps you can take that may help improve saliva flow include:-

Sucking on sugar-free candy or chewing sugar-free gum.
Drinking plenty of water to help keep your mouth moist.
Protecting your teeth by brushing with a fluoridetoothpaste, using a fluoride rinse, and visiting your dentist regularly.
Breathing through your nose, not your mouth, as much as possible.
Using a room vaporizer to add moisture to the bedroom air.
Using an over-the-counter artificial saliva substitute.

Hope I have answered your query.

Hello & welcome,

In your case, dry mouth seems to be exactly due to mouth breathing habit as you mentioned.
Having dry mouth on exertion is not abnormal exactly. But if is it severe, then underlying cause should be found & treated accordingly.

Reasons for dry mouth include systemic conditions like Diabetes being major, anti allergic drugs like cetrizine or salivary gland infection.

Dry mouth may be presented due to Oral submucous fibrosis caused by the use of tobacco even in the form of smoking, eating spicy foods regularly.

It may occur even due to dehydration. But important is, Dry mouth if not treated properly can lead to thickening of collagen fibers ( elastic fibers ) of oral mucosa. It may even make the oral mucosa prone to infection & thereby damaging its elasticity.

Visit your dentist for proper clinical examination to rule out any other systemic condition.
Drinking plenty of water to maintain fluid level of the body to optimum is of utmost imporant.

Avoid smoking or chewing of tobacco if habitual to same.
Avoid spicy food as it would lead to burning sensation spreading in all over mucosal surface thereby aggravating the condition.

Artificial saliva substitute will be given to you only if dentist feels that condition is severe & can be treated without it.

Keep your oral cavity always clean by means of proper cleaning habits.

Remember, don't use mouth wash unless prescribed by your dentist as it tends to stain your mucosa along with teeth & tongue specially in dry conditions.

Orthodontic appliance may be offered to you to wear by your dentist to break the habit of breathing via mouth.

Take care

Dentist Dr. Geoffrey Ward's  Response
Hello and thank you for your question.
The dry mouth that is occuring could be due to decreased salivary flow and "wind" irritation to your uvula. Take sips of water throughout your workout. You can also try gum with xylitol and dry mouth mouth rinse before your work out.

If these issues continue with the advice I gave you, I recommend going to an ENT specialist to have your throat inspected. If you have increased in weight lately, the extra weight can cause airway restrictions.

Best wishes, good health and continue working out! you are making your first steps to success!

General & Family Physician Dr. A K M Wasim Rahman's  Response
Dear Stuart,
An EKG(ECG) and echocardiography is advisable, as this may be due to some cardiac cause. Do you feel any chest pain during the episode or any other time?
If above investigation - normal then we can exclude cardiac cause.
The next most likely thing is GI cause- to exclude that 24 hour ph and Upper GI endoscopy can be done.
Third possibility may be Respiratory Cause.
Consult a physician as soon as possible.
