What do chills and nausea mean?

Nausea may come from the same illness that causes chills, or from fluid loss after vomiting or diarrhoea. Fever, body aches, and cough can occur with Influenza. Nausea with pain in the back or side, fever, or urinary changes can accompany a Kidney Infection or Urinary Tract Infection. Dengue Fever and Malaria are possible concerns after relevant travel and may involve fever, chills, headache, or body aches. Pneumonia can cause chills and nausea alongside cough or shortness of breath. These symptoms do not point to one diagnosis by themselves; age, pregnancy, recent food or medicine exposure, and hydration are useful details.

Take small, frequent sips of water or an oral rehydration drink if you can keep fluids down. Rest in a cool, comfortable place and choose plain foods only when your stomach settles. Check your temperature and note vomiting, diarrhoea, abdominal pain, urine output, and the time symptoms began. Avoid alcohol and do not start antibiotics or anti-nausea medicines without professional advice. If pregnancy is possible, mention it before taking medicines.

Seek emergency help for severe or worsening abdominal pain, confusion, fainting, difficulty breathing, blood in vomit or stool, a stiff neck, or inability to keep fluids down. Arrange prompt medical review for signs of dehydration such as very little urine, dizziness on standing, a dry mouth, or unusual drowsiness. Chills with fever after travel to a malaria area need timely assessment. Rapid deterioration with confusion, breathlessness, or cold clammy skin may indicate Sepsis and requires emergency care.

Tell your doctor when nausea and chills started, what you have eaten, whether anyone else is ill, and which medicines or supplements you use. Ask how much fluid to take, what warning signs matter for you, and whether your symptoms call for tests for infection, pregnancy, or another cause.
