Direct and indirect effects of obesity on the kidney
Hydration and avoiding strenuous activity for a day can also help

Foods to prioritise for their fibre content and overall nutritional value include: Whole grains : Oats, barley, quinoa, brown rice, wholemeal bread, and whole-wheat pasta provide sustained energy and both types of fibre Legumes : Lentils, chickpeas, black beans, and kidney beans offer protein alongside substantial fibre content Vegetables : Broccoli, Brussels sprouts, carrots, sweet potatoes, and leafy greens supply vitamins, minerals, and fibre Fruits : Berries, apples (with skin), pears, oranges, and kiwi fruit provide soluble fibre and antioxidants Seeds and nuts : Chia seeds, flaxseeds, almonds, and walnuts offer healthy fats alongside fibre (keep to a small handful for portion control) Psyllium husk : A concentrated fibre supplement that can be added to smoothies or yoghurt (take with plenty of water and separate from other oral medicines by at least 2 hours) Foods to limit or avoid , particularly during the initial treatment phase or when experiencing digestive symptoms: Ultra-processed foods : These typically contain minimal fibre and may worsen blood glucose control High-fat, greasy foods : These can exacerbate nausea and slow digestion further, compounding GLP-1 effects Excessive simple sugars : Sweets, sugary drinks, and refined carbohydrates offer no fibre and may cause blood glucose fluctuations Alcohol : This can increase nausea risk and provides empty calories that may undermine weight management goals

Caffeine metabolizes through the liver's cytochrome P450 system, while tirzepatide acts on peptide receptors in the gut and braintwo entirely separate pathways
When blood glucose levels are elevated, GLP-1 binding to beta-cell receptors triggers intracellular signaling cascades that enhance insulin synthesis and release
