️ The symptoms that don't announce themselves

Hair loss, fatigue, weakness, dizziness, and feeling cold may become more likely during prolonged periods of inadequate nutrition.

Vitamin D's disappearing food sources

Vitamin D intake often falls because people eat substantially less overall once appetite drops significantly. Fatty fish, fortified dairy, egg yolks, and fortified foods are among the major dietary vitamin D sources people gradually stop eating as often. Vitamin D deficiency is already common worldwide. 🐟 Salmon, sardines, 🥚 eggs, fortified yogurt, and fortified milk are often easier to keep eating than very large meals during slower gastric emptying. Small balanced meals with protein and fat

The meal that still counts

🥚 Eggs, 🥛 Greek yogurt, 🐟 salmon, sardines, beans, 🫘 lentils, soup, fruit, and softer balanced meals generally support nutrition better than relying primarily on shakes and snack bars. Small balanced meals eaten consistently may better support energy and overall nutrition than eating very little throughout the day. Warm rice bowls, soups, 🥚 eggs, yogurt, oatmeal, and softer protein meals are often easier to tolerate during higher-nausea periods.

The most practical vitamin D foods

Fatty fish like 🐟 salmon, sardines, trout, and mackerel are among the richer natural food sources of vitamin D. Egg yolks, fortified dairy, fortified milk alternatives, and some mushrooms also provide smaller amounts of vitamin D. 🐟 Salmon rice bowls, 🥚 eggs with toast, yogurt parfaits, fortified smoothies, and soup-based meals are often easier to tolerate during reduced-appetite periods.

Many people gradually stop eating enough protein, vegetables, dairy, beans, fruit, and whole meals once fullness increases substantially. Vitamin D, B12, iron, calcium, and electrolytes are among the nutrients most commonly affected — not because the medication causes deficiency, but because the volume of food shrinks dramatically and the gaps follow quietly.
