Five 'common warning' signs of blood clots – doctor says to seek help 'right away'

Blood clots are a double-edged sword. When the gel-like clumps spur on in response to bleeding, they can prove useful. However, not all clots are to be welcomed. Blood clots that develop in your veins, also known as deep vein thrombosis, can be dangerous. Fortunately, a doctor has shared the five red flags to look out for.

When symptoms do appear, it’s important to act promptly and seek medical help “right away”.

The doctor shared that the following are “common warning” signs, pointing to blood clots in veins.


A swelling that usually occurs in the leg, ankle or foot is considered one of the tell-tale signs of deep vein thrombosis.

Dr Abu-Bakr said: “On its own, this symptom can be mistaken for something else, such as an insect bite. 

Warmth or redness

DVT may cause your skin to feel warm in the affected area around where the clot is in the body.

Dr Abu-Bakr said: “This warmth is noticeable by the difference in temperature between the affected area compared to surrounding body parts.”

Discolouration in the skin

The affected area may also change its usual tint and become a pale colour with a red or blue shade.

The doctor added: “If you experience any of these symptoms, especially if you have risk factors for DVT, it’s important to seek medical attention right away to prevent complications.”

The good news is that there are several ways to reduce your risk of blood clots in veins.

The doctor recommended the following strategies:

  • Use compression stockings to help improve blood flow in the legs (particularly helpful when it comes to long-haul flights)
  • Stay active to address DVT risk factors by helping you maintain a healthy weight, boosting circulation, improving lung function, and strengthening muscles 
  • Stay hydrated to reduce the risk of blood thickening
  • Avoid prolonged sitting or standing (if you sit or stand for long periods of time, take frequent breaks to stretch your legs and move around).

The doctor added: “It’s important to note that these strategies may not be effective in all cases, and some people may require additional interventions, such as medication or surgery, to prevent DVT. 

“Talk to your healthcare provider about the best strategies for your individual situation.”
