Summer Care for Diabetes in Hyderabad’s Heat
Hyderabad summers can be punishing, with temperatures that often climb above forty degrees. For
people with diabetes, heat is more than an inconvenience. Dehydration raises blood sugar, some
medicines increase the risk of fluid loss, and heat can damage insulin and testing supplies. With a few
precautions, you can stay safe and comfortable through the hottest months.
How Heat Affects Diabetes
- Dehydration concentrates the sugar in your blood and can raise readings.
- Sweating and a poor appetite may lead to low sugar if you take insulin or sulfonylureas.
- Heat widens blood vessels and can lower blood pressure, causing dizziness, especially with blood
pressure medicines. - High sugar makes you pass more urine, which adds to fluid loss.
- Nerve damage can reduce sweating and heat awareness, making heat exhaustion more likely.
Medicines That Increase Dehydration Risk
Diuretics, SGLT2 inhibitors, and some blood pressure medicines can increase fluid loss. During very hot
spells or illness, ask your doctor whether your doses need adjusting. Do not stop medicines on your
own.
Staying Hydrated
- Drink water regularly through the day, even if you do not feel thirsty, unless your doctor has restricted
fluids. - Buttermilk without sugar, lemon water without sugar, and clear soups are good choices.
- Coconut water can be taken in moderation, as it contains natural sugar and potassium.
- Avoid cola, packaged juices, energy drinks, and sweetened sherbets.
- Limit tea, coffee, and alcohol, which can promote fluid loss.
- Carry a water bottle when you go out.
Protect Your Insulin and Supplies
Heat can spoil insulin and test strips. Do not leave insulin in a parked car, near a stove, or in direct
sunlight. Use an insulated pouch when travelling, and store unopened vials as the label advises. Keep
glucometers and strips away from heat, and replace strips that were exposed to high temperatures. If
insulin looks cloudy, clumpy, or discoloured, or does not work as expected, do not use it.
Eating in the Heat
Choose light meals with vegetables, curd, salads, and pulses. Avoid heavy, oily, and spicy foods, and
do not skip meals even if your appetite is low. Fruits such as guava, papaya, and watermelon in small
portions help hydration. In mango season, keep portions small and eat them as a snack, not after a
heavy meal.
Exercise in Hot Weather
Walk in the early morning or late evening, when it is cooler. Wear light, loose cotton clothing and a hat,
and carry water. Choose indoor exercise on very hot days. Check your sugar before and after exercise
if you take insulin or sulfonylureas, and stop if you feel dizzy or faint.
Foot Care in Summer
Hot pavements can burn numb feet in minutes. Always wear closed footwear when going outside, never
walk barefoot on terraces or roads, and avoid sandals that expose the skin if you have neuropathy.
Check your feet daily for blisters, and moisturise dry skin.
Warning Signs of Heat Illness
- Heavy sweating, headache, dizziness, nausea, and muscle cramps, which indicate heat exhaustion.
- Hot, dry skin, confusion, fast pulse, and fainting, which indicate heat stroke and need emergency
care. - Very dark urine and little urine, which indicate dehydration.
- Blood sugar readings that are unusually high or low
If you notice these signs, move to a cool place, drink fluids, check sugar, and seek medical help.
