How to Prevent Dry Mouth While Fasting: Tips and Remedies

How to Prevent Dry Mouth While Fasting

Dry mouth, or xerostomia, is a common side effect of fasting. It occurs when saliva production drops, leaving your mouth feeling parched.

While not generally dangerous on its own, dry mouth can cause bad breath, dental issues, trouble speaking and eating, and increased thirst. Fortunately, there are ways to minimize dry mouth during a fast.

Causes of Dry Mouth During Fasting

Fasting is the practice of voluntarily abstaining from some or all food and drink for a set period of time. Common types of fasting include:

• Intermittent fasting
• Water fasting
• Juice fasting
• Religious fasts

When you fast, especially for longer periods, your body responds by slowing metabolic processes to conserve energy. This leads to reduced saliva production, a major cause of dry mouth.

Dehydration can also contribute to dry mouth while fasting since you are consuming little to no fluids. Finally, some medications can worsen dry mouth as a side effect.

Tips to Prevent Dry Mouth During a Fast

You can take steps to stimulate saliva flow and keep your mouth moist during a fast. Here are some effective tips:

Drink Water

Staying hydrated is key. While plain water is best, you can also drink unsweetened tea, coffee, sparkling water or bone broth during fast periods.

Chew Sugar-Free Gum

Chewing gum promotes saliva production. Choose a sugar-free variety to avoid breaking your fast.

Suck on Ice Chips

Sucking on small ice chips provides hydration and moisture. Freeze water, broth or tea into ice cubes for this purpose.

Use a Humidifier

Dry air exacerbates dry mouth. Run a humidifier at home and work to add moisture to the air.

Rinse and Gargle

Swish water, mint tea or salt water around your mouth to coat oral tissues.

Avoid Caffeine and Alcohol

Caffeinated and alcoholic drinks are dehydrating. Its best to avoid them or limit intake while fasting.

Stimulate Saliva with Citrus

Sucking on a lemon wedge signals your salivary glands to produce more spit.

Use a Saliva Substitute

Over-the-counter oral sprays and gels provide temporary relief when natural saliva is lacking.

Dry Mouth Remedies to Use During Eating Windows

On non-fasting days or during eating windows, try these additional remedies:

Sugar-Free Lozenges

Lozenges provide long-lasting lubrication and moisture for dry mouth.

Xylitol Gum and Mints

Xylitol helps stimulate saliva flow. It comes in many oral products.

Oral Rinses

Specialized oral rinses like Biotene provide longer lasting dry mouth relief between meals.

Drink Fluids Often

Sip water, herbal tea, broths and other hydrating fluids all day long.

Eat Moist Foods

Consume foods with high water content like fruits, veggies, yogurt, soups and smoothies.

Avoid Sugary and Starchy Foods

These foods increase risk for cavities, fungi and gum disease if dry mouth is present.

Use a Nighttime Humidifier

Combat overnight dryness by using a humidifier in your bedroom while sleeping.

Lifestyle Changes to Prevent Chronic Dry Mouth

Making certain lifestyle modifications can also help minimize dry mouth:

Quit Smoking

Smoking cigarettes or vaping causes dry mouth. Quitting improves saliva flow.

Practice Good Oral Hygiene

Brush and floss thoroughly after meals and before bed. See your dentist regularly.

Avoid Medications That Cause Dry Mouth

If possible, ask your doctor for alternatives to prescriptions that list dry mouth as a side effect.

Treat Any Other Health Conditions

Issues like anxiety, diabetes, hypertension, Alzheimers and autoimmune disease can impact saliva production.

Drink Less Caffeine and Alcohol

Limit intake of caffeinated and alcoholic beverages, which are dehydrating.

Be Careful With Breathing Through Your Mouth

Mouth breathing leads to faster evaporation of moisture. Try breathing through your nose more often.

When to See Your Doctor

Schedule an appointment with your healthcare provider if:

• Dry mouth symptoms dont improve with home remedies
• Dry mouth interferes with eating, speaking or sleeping
• You experience persistent thirst along with dry mouth
• You have sores, ulcers or other lesions in your mouth

Severe dry mouth that persists could be a sign of an underlying illness requiring treatment. Your doctor can help identify the cause and provide specialized solutions tailored to your situation.

The Bottom Line

Dry mouth is a nuisance but common side effect while fasting. Sipping fluids, chewing gum, using oral moisturizing products and adding humidity to your environment can provide relief. Lifestyle changes may also be needed to address chronic dry mouth issues.

Pay attention to symptoms and talk to your doctor if home remedies arent giving enough relief. With the right prevention tips, dry mouth doesnt have to be an inevitable part of your fasting experience.
