Simplify: Avoid rich, greasy, spicy, or heavy foods during the first few days of a new dose.
Environment: Seek fresh air and practise slow, deep breathing.
Vomiting
Sip slowly: Use water or herbal teas frequently to prevent dehydration.
Bland diet: Stick to simple foods like dry toast or crackers once you feel able to eat.
Consultation: You must consult your MedExpress clinician or prescriber before using oral rehydration salts, to ensure they are appropriate for you.
Diarrhoea
Fluid replacement: Prioritise consistent fluid intake.
Rest: Allow your body time to recover.
Rehydration: Only use oral rehydration salts if specifically recommended by your MedExpress clinician or prescriber.
Constipation
Fibre and fluids: Increase your intake of water and fibre-rich foods, such as vegetables and whole grains.
Movement: Stay physically active to help stimulate your digestive system.
Supplements: You must consult your MedExpress clinician or prescriber before starting any supplements, such as glucomannan, to check for suitability and safe dosing.
