Varicose veins - This Morning doctor explains when to see a GP
Doctor Zoe Williams has shared her insights on varicose veins, explaining what they are and when it's time to seek GP help. Often dubbed 'spider veins', these generally appear twisted and swollen at the skin's surface, often on the legs.
While they are fairly common and usually quite harmless, they may occasionally give rise to more serious problems, including bleeding or blood clots. "I mean, they are quite common," Dr Zoe said on ITV's This Morning earlier in the week.
"They affect roughly one in five people, and essentially it's a stretched, baggy vein. So, if you think about our arteries, they are under lots of pressure.
"The blood gets swished around the body, the veins, if you think about a vein that starts on your foot, that blood's got to get back up to your heart. But there's not a lot of pressure.
"So, in our veins, we have these valves that mean that blood can only flow one way. So, blood flows up and then it is caught by the valves to stop it back flowing.
"If those valves are not working properly, then blood can go backwards, and it can pool in the lower veins, and that can stretch them, and then they can get sort of baggy, and [it gives] this sort of loose, twisted appearance. And they tend to affect the legs most commonly, but they can actually happen anywhere."
Jumping into the conversation, show host Dermot O'Leary asked: "Because the legs are so far away from the heart?" To which, Dr Zoe replied: "Yeah, so there is more, they've got to fight harder. That blood's got to fight harder to get up in the body.
"So, they are, yeah, they are pretty common, and that's what causes them, it's this back pressure."
While anyone can get varicose veins, they are more common among people who are:
Overweight
Older
Pregnant
Spend a lot of time standing or sitting
Women
Have other family members with varicose veins
Have had deep vein thrombosis (a type of blood clot)
Both Dr Zoe and other specialists also agree that people in specific careers are more prone to varicose veins, too. This is especially the case if they are constantly standing up or walking, which can put heavy pressure on leg veins.
Poor circulation and muscle fatigue are two other consequences of standing too long. "So, nurses, teachers can more commonly get them," Dr Zoe continued. "And if you are carrying excess body weight, that can make you more likely to get them as well.
"And pregnancy is one of the biggest reasons."
Although NHS treatment for varicose veins is not available for cosmetic purposes, it is accessible if they present health risks or lead to complications. Dr Zoe outlined a few situations that may apply:
The veins are prone to bleeding
You have ulcers linked to the veins
You are experiencing dry, flaky skin texture changes in relation to the veins
The veins feel heavy, painful or uncomfortable
You have phlebitis (a clot in the superficial vein)
Anyone concerned about the risk associated with varicose veins is encouraged to seek GP advice. For more information, head to the NHS website.

Patients will suffer most if doctor strikes resume, NHS bosses warn
NHS bosses have warned that patients will be the ones to 'suffer most' from another wave of doctors' strikes as they nervously await the results of a ballot. The British Medical Association is expected to announce results of its ballot of about 50,000 resident doctors, who were formerly known as junior doctors, on Tuesday. The ballot closed at 12pm on Monday and if passed, would give resident doctors a six-month mandate to call strike action until the New Year, with strikes held from July 21 at the earliest. The result is expected to be close, with NHS bosses hopeful that turnout may not pass the 50 per cent threshold required for industrial action. However, BMA leaders have said that they are confident it will pass and that doctors are 'excited to go again'.

Measles symptoms you should know and when to call 999
The infection can be prevented by having the MMR vaccine, but if you do get measles, it's worth knowing the symptoms to look out for, when you need to call for medical help and how to avoid spreading it further. The NHS website explains: 'Measles usually starts with cold-like symptoms, followed by a rash a few days later. Some people may also get small spots in their mouth.' What are the measles symptoms you should know about? Cold-like symptoms can include a high temperature, a runny or blocked nose, sneezing, a cough or red, sore and watery eyes. Measles cases are rising in England. You can still ask your GP practice for the MMR vaccine if your child has missed either of these 2 doses. For more info ➡️ — NHS (@NHSuk) January 19, 2024 You might start to notice small white spots in the mouth, including inside the cheeks and on the back of the lips. It's not unusual for these spots to last for a few days. Once you've had the cold-like symptoms for a few days, you will probably start to develop a rash, which usually starts on the face and behind the ears. It then spreads to the rest of the body, the NHS explains. The rash isn't usually itchy, and sometimes the measles rash can be raised and join other parts to make blotchy patches. On white skin, the rash often looks red or brown, but it can sometimes be harder to see on black or brown skin. The NHS adds: 'It's very unlikely to be measles if you've had both doses of the MMR vaccine or you've had measles before.' When should you ask for an urgent GP appointment or call 999? The NHS outlines when you should ask for an urgent GP appointment or call 111, including if: you think you or your child may have measles your child is under 1 year old and has come into contact with someone who has measles you've been in close contact with someone who has measles and you're pregnant or have a weakened immune system you or your child have a high temperature that has not come down after taking paracetamol or ibuprofen you or your child have difficulty breathing – you may feel more short of breath than usual your baby or young child is not feeding well, or taking less feeds or fluids than usual you or your child are weeing less than usual (or your baby has fewer wet nappies) you or your child feels very unwell, or you're worried something is seriously wrong The health service added: 'Measles can spread to others easily. Call your GP surgery before you go in. They may suggest talking over the phone. 'You can also call 111 or get help from 111 online.' Heat rash is common during hot weather. It is uncomfortable, but usually harmless. It usually gets better on its own after a few days. Here are some tips to help you check if you have heat rash – and advice on how to treat it. More info ➡️ — NHS (@NHSuk) June 21, 2025 You should call 999 or go to A&E if you or your child has measles and: have a seizure (fit) severe difficulty breathing – you're gasping, choking or not able to get words out (babies may make grunting noises or their stomach may suck under their ribcage) are unable to stay awake – cannot keep their eyes open for more than a few seconds suddenly become confused – your child may be very unsettled, behaving differently, or crying non-stop your child is limp, floppy or not responding normally – their head may fall to the side, backwards or forwards, or they may find it difficult to lift their head and focus on your face a rash that does not fade when you press a glass against it a stiff neck or find light uncomfortable or painful How is measles spread? Measles will spread when a person who is infected coughs, sneezes or breathes. The NHS said: 'You're infectious from when you first have symptoms (around 4 days before the rash appears) until 4 days after you get the rash.' Recommended reading: If you have measles, it's advised that you wash your hands often using soap and warm water, use tissues to cough and sneeze into and throw them away in the bin when finished with them. It's important that you avoid sharing cutlery, cups, towels, clothes and bedding. You can find out more about measles via the NHS website, linked above.

Swinney an ‘analogue politician in a digital age' says Streeting
John Swinney, the First Minister, has been described by the UK Health Secretary as an 'analogue politician in a digital age' in a row over the Scottish Government's failure to create an NHS app. Wes Streeting said there was 'no excuse' for the devolved government not to have introduced an app that allows patients to book appointments with their GP, order prescriptions and manage hospital appointments. A similar app was rolled out in England six years ago. Plans to create an NHS Scotland app are underway but are currently limited to a trial for dermatology patients in NHS Lanarkshire. A national rollout is not expected before the end of the decade. Mr Streeting warned patients in Scotland are 'missing out' and said it showed why Scotland 'can't afford a third decade of the SNP'. He is the first senior Westminster politician to publicly criticise the running of Scotland's NHS, which has been under fire for lengthy waits. Mr Streeting said: 'The UK Labour Government is embracing technology to deliver a better NHS for patients and their families, giving them more control and transparency over their treatment. 'In John Swinney, the SNP have an analogue politician in a digital age, and patients in Scotland are missing out. 'The SNP have record funding and complete control of the NHS in Scotland, there's no excuse for this, and it just shows why Scotland can't afford a third decade of the SNP and needs a new direction with Anas Sarwar as first minister.' It is not the first time that Scotland's First Minister has been accused of being slow to bring the Scottish NHS into the 21st century. Earlier this year, Ian Murray, the Scottish Secretary, made similar remarks after GPs said they looked 'on with frustration' at the digital health tech divide between England and Scotland, citing the delay in launching tools such as the NHS Scotland app. Mr Streeting has pledged to improve the use of technology in the NHS south of the border and last week announced improvements to the country's NHS app, which already has 35 million users. Sir Keir Starmer, the Prime Minister, said the app would 'become, as technology develops, like having a doctor in your pocket, providing you with 24-hour advice, seven days a week'. The 'supercharged' version of the app is promised to be delivered by 2028 and is expected to allow patients to book and check hospital appointments, interact with specialists or visit an 'AI doctor' for advice. An app for the Scottish health service, announced in 2021, is not expected to launch on a trial basis until December. Its functionality will initially be severely restricted, with its only practical purpose being to allow dermatology patients served by one health board, NHS Lanarkshire, to be notified of appointments. If successful, rollouts will continue in other areas until its full introduction in five years. 'Sustained improvements for patients' According to the latest official health statistics, the number of patients waiting more than 78 weeks for treatment in Scotland has increased to 38,070, while in England the figure has halved to 1,154. Cancer treatment waiting time standards are also being missed. A spokesperson for Neil Gray, the Scottish Health Secretary said: 'Scotland's planned online app is for both health and social care and we will launch it in Lanarkshire by the end of 2025. 'National rollout will commence through 2026 and we will publish a national rollout plan later this summer. 'We will leave Labour to carry out personal attacks – the SNP Government's focus is on putting in place the lasting solutions which will deliver sustained improvements for patients. 'As Wes Streeting knows, Scotland's core A&E performance has been the best in the UK for the last 10 years, we have more GPs per head than south of the border, and we are building on this with record funding for health and social care this year.'
