In some cases,symptoms of more severe sepsis or septic shock (when your blood pressure drops to a dangerously low level) develop soon after. These can include: feeling dizzy or faint, a change in mental state (e.g. confusion or disorientation), nausea and vomiting, slurred speech, less urine production than normal (e.g. not urinating for a day) and cold, clammy, pale or mottled skin.
Sepsis is often diagnosed based on basic measurements including temperature, heart rate, breathing rate and a blood test. If sepsis is detected early and hasn’t yet affected vital organs, it may be possible to treat the infection at home with antibiotics.
