عادات وأطعمة تهدد صحة الكلى في رمضان.. نصائح طبية لصيام آمن

Interest in kidney health increases during the holy month of Ramadan, as they are subjected to additional stress due to changes in drinking and eating patterns, and abstaining from food and drink for long hours.

Doctors and specialists in kidney diseases and nutrition warn that some common habits during Ramadan may lead to dehydration, high blood pressure, the formation of stones, or the exacerbation of pre-existing kidney problems, especially in patients with renal failure or those with a medical history.

Habits and Foods That Affect the Kidneys in Ramadan

1 - Dehydration and insufficient fluid replacement

According to PubMed Central, not drinking enough water (preferably 2 - 3 liters or more depending on the condition) between iftar and suhoor increases urine concentration, raising the risk of kidney stone formation and urinary tract infections.

2 - Excessive salty foods

Pickles, fast food, processed meats, and salted nuts raise sodium levels, causing fluid retention, high blood pressure, and increased pressure on the kidneys.

3 - High consumption of animal protein

Studies confirm that excessive consumption of red meat and grilled chicken in large quantities increases the burden on the kidneys, raises uric acid levels, and may lead to waste accumulation.

4 - Diuretic beverages

Nutrition experts indicate that coffee, tea, soft drinks, and cola draw fluids from the body and increase dehydration, which affects kidney function; therefore, it is advised not to overconsume them between iftar and suhoor.

5 - Excessive intake of foods rich in potassium and phosphorus

Doctors warn chronic kidney patients against excessive consumption of foods high in potassium and phosphorus such as bananas, dates in large quantities, oranges, mangoes, tomatoes, potatoes, spinach, legumes, and dairy products, which may dangerously elevate these mineral levels.

6 - Foods rich in oxalates

Excessive consumption of spinach, nuts, and chocolate may contribute to kidney stone formation.

7 - Excessive sugars and fats

Heavy Ramadan sweets and fried foods lead to weight gain and increased sugar and pressure levels, which harm the kidneys in the long run.

Medical Tips for Maintaining Kidney Health During Ramadan

Experts confirm that fasting can be safe for healthy individuals if these tips are followed, while chronic kidney patients need individual assessment from a specialist doctor.

Here are the main tips for maintaining kidney health:

- Drink plenty of water and unsweetened fluids between iftar and suhoor.
- Do not skip the suhoor meal, and make it balanced with complex carbohydrates (whole grain bread, oats) and moderate protein and vegetables.
- Start iftar with a moderate amount of dates (1 - 3 pieces) or low-potassium fruits like apples or oranges in limited quantities.
- Reduce salt to a minimum, and replace salty foods with natural spices.
- Choose moderate protein sources (chicken, fish, eggs in appropriate amounts) and avoid overconsumption.
- Include water-rich vegetables and fruits like cucumbers, watermelon (in moderation), and lettuce.
- Avoid exposure to heat and intense physical exertion during the day.
- Consult a kidney doctor before fasting if you suffer from kidney failure, stones, or high blood pressure.
