Fasting is a cherished tradition embraced by millions around the world for various religious, spiritual, and health reasons.

In South Africa's culturally rich landscape, this practice is particularly prominent during the holy month of Ramadan, when approximately one million Muslims partake in fasting from sunrise to sunset.

While the spiritual and physical gains from fasting are often celebrated, an unwelcome side effect of bad breath can dampen the experience.

Recent surveys among South African dental professionals reveal that fasting is a significant contributor to halitosis.

Dr Ridhwaan Haffajee, a skilled prosthodontist from Matrix Dental Specialists in Cape Town, affirms, "Whatever the reason you fast, it puts you at a higher risk of halitosis."

Does foul breath have to be endured during this spiritually significant time? Experts argue otherwise; with the right oral care routine and slight modifications to hydration and dietary habits, it is possible to maintain fresh breath throughout the fast.

Understanding the causes of bad breath during fasting

One primary reason for the onset of bad breath during fasting is decreased saliva production. When food and water intake is limited, saliva, the mouth's natural defence system, decreases.

Haffajee elaborates, "Saliva neutralises acids and washes away bacteria and food particles."

Consequently, when saliva levels drop, bacteria thrive, leading to an increase in volatile sulfur compounds (VSCs) which are notorious for causing bad breath.

A common consequence of fasting is dehydration, which worsens this issue. "Not drinking water during fasting hours further depletes saliva production, worsening dry mouth and heightening the risk of bad breath," Haffajee explains.

Additionally, prolonged fasting may induce ketosis, a metabolic condition where fat becomes the primary energy source instead of carbohydrates, sometimes resulting in a distinctly fruity or metallic breath odour.

The social ramifications of bad breath

Beyond the medical implications, bad breath bears significant emotional and social consequences.

"Bad breath can substantially affect a person’s self-esteem, particularly in social and professional environments," highlights Mohammed Uzair Bhamjee, a counselling psychologist at Soulful Psychology.

"People who are self-conscious about their breath may avoid conversations or withdraw from social interactions altogether, leading to anxiety, self-doubt, and even isolation," says Bhamjee.

For many South Africans, especially those fasting in group or family settings, maintaining confidence and social connections is vital.

Addressing and preventing bad breath can help you focus on the deeper meaning of fasting without distraction or discomfort.
