Dubai: Health experts in the UAE have highlighted how to prevent dehydration during Ramadan.

Tweaking the pre-dawn suhoor meal to start the day’s fast, and the sunset iftar meal taken to end it, with the right amount of hydrating fluids can make fasting easier, advise doctors.

This Ramadan has come on the brink of summer and will see residents fasting around 14 hours each day, leaving only an eight-hour window to end the fast, pray, hydrate and rest. Knowing the right kind of foods for nutrition and fluids for hydration, will help people observe the month with the right spirit, stamina and energy.

What is dehydration?

Dehydration is the loss of water from our bodies at a rate that is faster than we absorb it. Juliott Vinolia, Clinical Dietician with Medeor 24/7 Hospital, Dubai, said: “Nearly 70 per cent of human body is water, which is lost in many metabolic processes that our body is involved in, such as perspiration, urination, breathing and so on. We require our cells to be hydrated with fluids that contain electrolytes such as potassium, calcium, magnesium, sodium and other vital minerals.”

What are electrolytes?

Vinolia added: “Electrolytes are minerals in the human body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help us balance the amount of water in our body and keep the minerals in the correct proportions to facilitate proper metabolism. Metabolism refers to the ingestion, digestion, absorption and assimilation of nutrients that we take in through food and water.”

It is vital to understand that the minerals in our body help us regulate nerve and muscle function, hydrate the body, balance blood acidity and pressure, and help rebuild damaged tissue, she said.

What happens with electrolyte imbalance?

Vinolia explained: “When we fast without proper preparation and go without food and water for long periods, we may experience dehydration. Therefore prior to the fast and after ending the fast, it is very important that we hydrate and replenish our bodies with the right kind of liquids. Not all liquids are similar. For instance, having caffeine or carbonated drinks is likely to dehydrate you more, while having plain water, or water-rich vegetables, clear vegetable soup, will replenish the lost minerals in your body.”

How much water do we need?

Dr Nasrullah Jakhrani, specialist internal medicine at Aster Clinic, said: “Daily fluid maintenance requirements for adults is approximately 1.5 to 2 litres of water. The majority of fluid loss occurs through urine, stool and perspiration. The exact amount of fluid loss cannot be measured but it is estimated to be around 600ml to 800 ml per day.”

He advised that it was therefore important for people embarking on a month-long fast to be mindful of the fluid intake during suhoor and iftar.

“Enough water intake is advisable during suhoor and iftar to avoid dehydration. A person must see to it that a total of 2-3 litres of water is consumed before or after fasting time. This fluid can be in form of water-rich vegetables and fruits such as cucumber, watermelon, or wholesome soups taken along with dense carbohydrates and high fibre foods to help a person maintain good hydration levels throughout the fasting hours. Even when a person ends the fast, he is advised to end with a small carbohydrate-dense piece of date, water and soup.”

Avoid certain foods

Dr Jakhrani cautioned residents to skip foods that could trigger dehydration. “While ending the fast people tend to overeat and have sugar-rich fruit juices and heavy, oily food. However, it is advisable to avoid spicy, fried and sugary food as this results in more electrolyte losses. People must also avoid too much caffeine in tea and coffee as these can also cause rapid dehydration the next day. Fasting in Ramadan is beneficial for our health if done properly,” advised Dr Jakhrani.
