What if oral rehydration therapy does not relieve dizziness?

Oral rehydration therapy can help when fluid or salt loss contributes to dizziness, but dizziness can also arise from a sudden blood-pressure drop, low blood sugar, an inner-ear problem, anaemia, medicine effects, infection, or a heart or nervous-system problem. The sensation may be spinning, light-headedness, or unsteadiness, and describing it accurately helps guide assessment.

Move slowly, avoid driving, climbing, and machinery, and have someone nearby if you feel unsteady. Sip the prescribed solution as directed if fluid loss is still possible, but do not force large amounts. Note when the dizziness began, what triggers it, whether standing changes it, and any new medicines or associated symptoms.

Call emergency services for fainting, new weakness or numbness on one side, trouble speaking, severe headache, chest pain, breathing difficulty, a fast or irregular heartbeat, confusion, or inability to walk safely. Seek prompt medical advice for persistent or repeated dizziness, hearing changes, ongoing vomiting, or reduced urination.

Ask whether dehydration is still present, whether blood pressure or blood tests should be checked, whether a medicine could contribute, and what activities or warning signs should change your next step.
