Blood clots: Energy drinks may increase risk

Blood clots are not intrinsically bad. In fact, they are beneficial when they form in response to an injury or a cut, because they stem bleeding. However, when blood clots form inside your veins without good reason, they can be a portent of serious complications. Poor dietary decisions can promote the formation of the latter type.

Worryingly, energy drink consumption may kickstart the mechanisms that lead to the formation of blood clots.

Energy drink consumption in the United States has more than doubled over the last decade, researchers in a study published in the Journal of Surgical Research.

They noted that intake of the popular beverage has been implicated in a host of cardiovascular complications, such as cardiac arrhythmias, myocardial infarction, and even “sudden cardiac death”.

In light of this, the researchers hypothesised that energy drink consumption may increase the risk of adverse cardiovascular events by increasing platelet aggregation, thereby resulting in an increased risk of thrombosis (blood clot in a vein).

They concluded: “Although larger clinical studies are needed to further address the safety and health concerns of these drinks, the increased platelet response may provide a mechanism by which energy drinks increase the risk of adverse cardiovascular events.”

General tips to reduce your risk

Leading a heart-healthy lifestyle offers the greatest buffer against heart complications.

One of the most robust preventative measures is to keep active – the NHS says to take regular walks.

“Drink plenty of water to avoid dehydration – you’re more likely to get a clot if you’re dehydrated,” advises the charity.

You should also:

  • Try to lose weight if you’re overweight
  • Wear flight stockings or flight socks to improve your blood flow on long flights – a pharmacist can advise you about this
  • Avoid drinking lots of alcohol.

Symptoms to spot

Symptoms of a blood clot include:

  • Throbbing or cramping pain, swelling, redness and warmth in a leg or arm
  • Sudden breathlessness, sharp chest pain (may be worse when you breathe in) and a cough or coughing up blood.

Blood clots can be life threatening if not treated quickly.

“111 will tell you what to do. They can arrange a phone call from a nurse or doctor if you need one,” adds the NHS.
