Does the stomach treat soup stock differently to water? Chemo side effects.

  • Does the stomach treat soup stock differently to water? Chemo side effects.

    Posted by Steve Spencer on June 7, 2026 at 3:27 am EDT

    My wife recently started her third course of chemo for her ovarian cancer. This time, they’re using Cisplatin and Gemcitibane.

    So far, the worst side effects have been extreme fatigue and stomach upset, mostly bloating, constipation and gas. The fact that she was advised to drink plenty of water post-chemo made this worse, it seems.

    Because she wasn’t eating and, because water seemed to add to the bloating, I made her a chicken soup that was mostly broth – i.e. very ‘thin’ (to aid hydration) but nevertheless nutritious. I used chicken and vegetable stock, along with mushrooms, celery and onion to add flavour without promoting gas, plus of course chicken meat. It is VERY watery though. More fluid than solids.

    It seems to have gone down well and she isn’t suffering so much bloating, despite consuming (what seems like) a sizeable qty of fluid.

    So I started to wonder. Does our digestive system treat stock (which has suspended solids and other nutrients in it) differently to plain old water? What does the stomach do with water? Does it simply pass it along? Does it hang onto stock/soup for longer, to mix it with acid before shipping it out? If so, does this make a difference in my wife’s case?

    • Liquids generally empty faster than solids, so a very watery soup usually moves through the stomach more easily than the same volume of plain water because it contains calories, electrolytes and small amounts of protein/carbohydrate that change osmolality and stimulate coordinated motility rather than simple distension.
    • Soups that are bland, warm, low‑fat and low‑fiber are also less likely to cause gas or delayed emptying than fibrous or fatty meals, so they commonly reduce sensations of bloating and are easier to tolerate during chemo.
    • Other contributors to the improvement your wife noticed: better oral tolerance (flavor encourages sipping), improved hydration/electrolytes, and slower, frequent sipping instead of gulping — all reduce distension and nausea.

    Bottom line: a very watery, mildly seasoned chicken‑vegetable soup is a plausible reason for less bloating and nausea compared with drinking plain water, though individual responses vary.

    Good luck to you and your wife, and my wishes for a swift healing!

      Here are three additional soup recipes that might be helpful to you. Bon apetit!

      3 Soup Recipes for Chemotherapy SideEffect Support

      Notes: adjust seasoning to taste; avoid strong spice if mouth/mucosa are irritated. Use pasteurized/duly cooked ingredients and follow any neutropenic or fluid restrictions advised by the care team.

      1) Gentle High‑Protein Chicken and Rice Soup (easy to swallow, bland-tolerant)

      – Ingredients (2–3 servings): 2 cups low‑sodium chicken broth, 1 cup cooked shredded chicken, 1/2 cup cooked white rice, 1 small carrot finely diced, 1 celery stalk finely diced, 1 tsp olive oil, salt to taste, a small pinch of black pepper (optional).

      – Method: Sauté carrot/celery lightly in oil 3–4 min until soft. Add broth and simmer 8–10 min. Add cooked rice and shredded chicken to warm through 3–4 min. Season gently. Puree with an immersion blender for smoother texture if swallowing/mouth pain is present.

      – Tip: Stir in 1–2 tbsp powdered milk or 1/4 cup Greek yogurt (if tolerated) for extra protein and calories.

      2) Nausea‑Friendly Gingered Carrot‑Lentil Soup (gentle anti-emetic flavor, nutrient-dense)

      – Ingredients (2–3 servings): 3 cups vegetable or chicken broth, 2 cups chopped carrots, 1/2 cup red lentils (rinsed), 1 tsp grated fresh ginger, 1 tbsp olive oil, pinch of salt, small pinch black pepper.

      – Method: Sauté carrots briefly in oil, add broth, ginger, and lentils. Simmer 15–20 min until carrots/lentils are soft. Blend until smooth. Serve warm (not too hot).

      – Tip: Ginger can reduce nausea for many people; start with small amounts and increase if it helps.

      3) Calorie‑Dense Creamy Potato‑Leek Soup (for weight maintenance/appetite)

      – Ingredients (2–3 servings): 3 cups low‑sodium broth, 2 medium potatoes peeled and diced, 1 leek white part sliced (cleaned thoroughly), 1 tbsp butter, 1/2 cup full‑fat milk or cream (or coconut milk), salt to taste, small pinch black pepper, optional 2 tbsp grated cheese.

      – Method: Sauté leek in butter until soft. Add potatoes and broth; simmer 12–15 min until tender. Blend until smooth, stir in milk/cream and cheese to enrich, warm gently (do not boil). Adjust seasoning.

      – Tip: Add 2–3 tbsp nut butter or 1/4 cup cottage cheese blended in for extra protein if dairy tolerated.

      Additional practical tips

      – Serve warm, not piping hot, to reduce oral discomfort.

      – Offer small, frequent portions (1/2–1 cup) if appetite is poor.

      – If neutropenic, use well‑cooked, pasteurized, and hygienically handled ingredients; avoid raw garnishes.

      – Check with the oncology team before adding herbal supplements, high‑dose ginger, or concentrated herbal extracts.

        Thanks very much @AaronAF , and I just cleaned away the stray html which was making your first note look untidy.

      You are so welcome! On behalf of a friend of mine who has pancreatic cancer, I recently asked my former acupuncturist [Houston, TX] what he recommended for this kind of cancer. Here is his English-as-a-second-language reply:

      “I suggest gentle exercise, happy mood and good appetite are all important to him. He can take acupuncture and TuiNa treatment once a week. I suggest he take Yi Yi Ren as his regular food in his most of meal. On the other hand, your friend has to keep his spirit up, keep appetite, and keep his body weight as usual.”

      I found some more information about Yi Yi Ren, which indicates that it would be appropriate for most kinds of cancer:

      “Use Yi Yi Ren as a general, supportive food/herb used across multiple cancer‑related patterns in traditional Chinese medicine (TCM)—not uniquely for pancreatic cancer. In TCM it’s commonly used to strengthen digestion, reduce dampness/edema, and support appetite and weight, so practitioners often suggest it for patients with cancer‑related poor appetite, cachexia, or inflammatory symptoms rather than as a tumor‑specific anticancer agent.”

      My former acupuncturist also agreed with me that daily practice of any style of Tai Chi and QiGong would be helpful. As a longtime practitioner [in Upstate NY] of QiGong and Tai Chi I believe QiGong would probably be easier to learn, and especially so online, than would Tai Chi. However, I believe taking either one of these would be a wonderful way for your wife to maintain a happy mood. If you are interested, I could direct you to a website that has many videos that demonstrate QiGong exercises.
