As the UK gears up for a scorching week, with temperatures set to hit 29 degrees in some parts of England, doctors have warned about the less obvious impacts of the sun – including migraines and swollen ankles. NHS GP Dr Ravina Bhanot explained that the heat can cause blood vessels to expand in an attempt to cool the body down, leading to swelling in the feet.
“When your veins get larger, it can cause fluid to leak into the surrounding tissue, especially around your ankles and feet,” she said. “With the vessels being a bit leaky and with gravity, it can cause ankles to be a bit more swollen.”
This is a common occurrence, particularly for those who spend a lot of time on their feet.
However, if the swelling is painful, one-sided, or not improving, NHS GP Dr Deepali Misra-Sharp advises seeking medical attention.
If you notice swelling in one or both of your ankles, feet, or legs, and it doesn’t improve with home treatments, or if the condition worsens, it’s advised to consult your GP, according to NHS guidelines. If the swelling is severe, red, hot to touch, or accompanied by a high temperature or diabetes, an urgent appointment should be sought or assistance from NHS 111, reports Surrey Live.
In case of shortness of breath, chest tightness, heaviness, pain, or coughing up blood, dial 999 immediately. These symptoms could indicate a blood clot in your lungs, requiring immediate hospital attention.
Dr Bhanot emphasised the importance of staying hydrated, particularly during warmer temperatures. She cautioned against excessive consumption of caffeine, alcohol, or fizzy drinks as they can lead to dehydration.
“My best tip is to drink small sips frequently throughout the day, ” she said.
“You can also add electrolyte sachets to your water if you exercise a lot or sweat a lot in the heat. If you notice your urine is quite dark, you probably need to drink more.”
Dr Misra-Sharp recommends drinking six-to-eight glasses of fluid daily as a general guideline for hydration.
However, during hotter weather or increased sweating, additional fluids are necessary, approximately two-and-a-half to three litres per day.
She advised: “The simplest way to check? Look at your wee – pale and straw-coloured is spot on. Darker? You probably need more fluids. Water is best, but tea, squash and water-rich foods like fruit help too.”
