EMERGENCY CARE
These summaries explain what a medical emergency can look or feel like, why it matters, and when 999 may be the right call. Acting quickly can make a real difference.
Sepsis
What it is and how it may present
Sepsis is a serious and potentially life-threatening reaction to infection, where the body’s response begins to injure its own tissues and organs. It can develop from infections such as pneumonia, urinary tract infections, abdominal infections, or skin wounds, and it does not always begin in hospital.
Symptoms can be varied and may develop gradually or suddenly. A person may feel very unwell, confused, extremely tired, or unusually cold or hot. Other signs can include fast breathing, a rapid heart rate, reduced urine output, mottled or pale skin, or a feeling that something is seriously wrong. In some cases, early symptoms are subtle and easy to dismiss.
Why this is a medical emergency
Sepsis can progress quickly and unpredictably. As the condition worsens, it can lead to organ failure, shock, and collapse. Early recognition and treatment are critical. Delays in assessment and treatment significantly increase the risk of serious complications and death.
Because the symptoms can resemble less serious illnesses at first, sepsis is sometimes recognised later than other emergencies. This makes timely medical assessment particularly important.
Why emergency services may be appropriate
Emergency services may be appropriate when sepsis is suspected, especially if symptoms are severe, worsening, or accompanied by confusion, breathing difficulties, or collapse. Rapid assessment and treatment allow infection to be identified, antibiotics and fluids to be started, and vital organs to be supported. Early intervention greatly improves outcomes.
