On World Water Day, we’re reminding Jamaicans that proper hydration is more than just a healthy habit. It is also an essential part of medication management. Whether you are managing hypertension, diabetes, asthma or another chronic condition, drinking enough water helps your body respond effectively to treatment. 

Clinical pharmacist Dr. Pheyona Oates Graham, says, “Hydration keeps organs, like your kidneys and liver, working well so they can process medication safely. Furthermore, it allows our bodies to absorb and use the medicine, while helping reduce side effects.ˮ

Without enough fluids, medications may not work as intended. Dehydration can worsen side effects such as dizziness or constipation and may contribute to low blood pressure, confusion or an electrolyte imbalance, particularly when combined with medicines that affect fluid or salt levels. Some tablets can also irritate the throat if swallowed with too little water.

How much water is enough?

For most healthy adults, the recommended fluid intake is 2-3 litres daily (about 6-8 glasses). However, individual needs vary based on size, weight, climate, physical activity, diet and certain medications. 

Persons with heart failure or kidney disease should follow fluid restrictions advised by their healthcare professional. It is also important to drink regularly throughout the day and watch for signs of dehydration. 

Warning signs to watch Dehydration can show up as: 

● Very dark urine or passing less urine than usual 

● Dry mouth or thirst 

● Headaches or muscle cramps 

● Dizziness or a fast heartbeat 

● Fatigue 

● Constipation 

● Confusion or reduced concentration.

Severe symptoms require urgent medical care. 

Simple ways to stay hydrated

Hydration is especially easy to miss in busy routines, during cooler weather (when thirst is lower), or in older adults who may not feel thirsty as strongly says Dr. Oates Graham. She recommends setting reminders, choosing fluids you enjoy such as water with lime, eating water-rich foods like soups and fruits, and increasing your intake in hot weather or when exercising. Checking your urine colour can also help. A pale yellow colour usually indicates good hydration. 

This World Water Day, make hydration part of your treatment plan. Small, consistent steps can make a meaningful difference to your treatment outcomes and overall health. Speak with your pharmacist or healthcare provider if you are unsure about your fluid intake needs.
