'I'm a doctor - here is the exact moment you should go to A&E if you have a fever'

A doctor has issued an urgent warning about when to head to A&E with a fever, highlighting that it could be indicative of a severe illness. While many fevers can be managed at home with rest and fluids, there are instances where medical intervention is crucial, he cautioned.

Speaking on the Spanish radio programme "Poniendo las Calles", Doctor Darío Fernández from the Legazpi Clinic advised listeners on the critical moments for seeking hospital care, as reported by Cope Radio online. Dr Fernández clarified that not all fevers should cause concern.

For mild or low-grade fevers, home treatments like resting, staying hydrated, and taking antipyretics might be enough to alleviate symptoms. However, a fever, which is typically over 37.8C, could point to a more significant issue if it comes with other severe symptoms.

The healthcare professional emphasised that in situations where a fever isn't the sole symptom and could indicate a serious illness, it's vital to get to the emergency room promptly.

'Extreme' malaise

One such concerning sign is a general feeling of "extreme" malaise accompanying the fever, which disrupts normal bodily functions, suggesting the possibility of a more serious infection or disease, he explained. If this includes symptoms like slurred speech, diarrhoea, vomiting and dizziness, for example, this could signal sepsis.

Intense headache

Another alarming symptom to watch out for is an intense headache. Dr Fernández has highlighted that an intense headache which doesn't subside with standard painkillers could be a red flag for serious health issues, such as meningitis or severe infections.

He pointed out that neck stiffness is particularly alarming when coupled with fever and is a critical reason to seek emergency care immediately.

Low blood pressure

Low blood pressure alongside fever might suggest the body is in shock or battling a significant infection. Dr Fernández warned that if fever is also accompanied by a rapid heartbeat (tachycardia) or breathing difficulties, these could be signs of a serious cardiovascular or respiratory problem that needs immediate medical intervention.

Seizures

Seizures occurring with a fever are among the most urgent medical crises. Dr Fernández emphasised the importance of getting anyone experiencing seizures during a feverish episode to go to A&E without delay.

However, Dr Fernández also clarified that not all fevers call for emergency treatment. Mild fevers without other worrying symptoms can often be managed at home with rest, plenty of fluids, and fever-reducing medication.

It's vital, though, to keep an eye on the fever's progression and get professional advice if symptoms deteriorate or if new, concerning symptoms emerge that could point to a complication.

The NHS reassures that while many factors can cause a high temperature, "It's not usually a sign of anything serious," according to the health service.

"It's often just caused by your body fighting an infection, such as a cold or flu. Sometimes it could be a sign of something more serious if your temperature is very high or will not come down."

If you have a temperature, NHS guidance suggests you should rest up, stay hydrated with plenty of fluids – aiming for light yellow and clear urine – and take paracetamol or ibuprofen if needed to ease discomfort. The health service advises calling 111 if your fever isn't improving or gets worse, despite home treatment.
