Low B12 or iron levels could cause or worsen restless legs syndrome, according to a doctor.
Dr Asif Ahmed, a UK-based doctor, explained the link in a video shared on his educational TikTok account @dra_says.
In his post, the expert shared the symptoms associated with the common problem, which can affect anyone at any age.
Dr Ahmed said: “The symptoms of restless legs can vary from a mild annoyance all the way up to depression, anxiety and lack of sleep.
“It’s very tricky to diagnose, but these are the criteria you must meet to get diagnosed with it.”
He then proceeded to list the criteria. The expert said:
- An uncontrollable urge to move your legs that may be associated with unpleasant feelings such as pins and needles, the feeling of shooting pains down your legs.
- The symptoms are far worse when you are at rest or lying down.
- Your symptoms are partially or completely better when you start moving or walking.
- Your symptoms are far worse at night.
- No other cause can be found on blood test or physical examination or in your history.
While there’s no obvious cause of the syndrome in most cases, as per the NHS, there may sometimes be a link to mineral and vitamin deficiencies.
Restless legs syndrome (RLS) is a neurological disorder that causes an uncomfortable feeling in the legs and an irresistible urge to move them.
RLS can severely disrupt sleep and is generally a lifelong condition, but there are treatments to ease symptoms, such as moving or rubbing your legs.
Dr Ahmed explained: “Some things we know make it worse or can potentially cause it are being low in iron, low in B12, pregnancy, or some medications.”
He added that it’s important to treat any known causes and that doctors may be able to prescribe medication if everything has been addressed but severe symptoms persist.
A doctor can diagnose RLS based on symptoms, medical history, family history, physical examination, and test results. If you have any concerns about your health, you should speak to your GP.
