You Are Eating. You Are Still Disappearing.
People keep saying it like a compliment. You have lost weight, they say, lucky you. Your clothes hang. Your face has changed. Someone in your family has told you to "just eat more", and you did — you forced down the rice, the eggs, the shakes — and the scale kept falling anyway.
So you concluded that you were failing at something as basic as eating. You were not. You were solving the wrong equation.
Intake Is Not the Bottleneck. Absorption Is.
Calories only count if they cross the intestinal wall. In Crohn's, that wall is the problem.
The small intestine absorbs through a vast folded surface of villi. Inflammation flattens and ulcerates that surface, and every ulcerated centimetre is a centimetre that absorbs nothing. Food passes through a shortened, damaged, fast-moving tube and leaves in the stool. You can eat five thousand calories a day and still starve if the surface that absorbs them is inflamed.
This is why "eat more" is not just unhelpful — it misidentifies the organ that is failing.
The Four Mechanisms Taking Weight Off You
Malabsorption. Lost villous surface, plus rapid transit, means fat, protein and carbohydrate are not fully taken up. Fat malabsorption produces pale, greasy, foul-smelling stool that is hard to flush — and it drags the fat-soluble vitamins A, D, E and K out with it.
Bile salt loss. The terminal ileum, Crohn's favourite site, is the only place bile salts are reabsorbed. Inflame it or remove it and bile salts are lost — so fat cannot be properly emulsified and absorbed, and the spilled bile salts irritate the colon into more diarrhoea.
Protein leaking out of you. Inflamed intestinal mucosa leaks albumin and other proteins into the lumen. This is protein-losing enteropathy. You are not merely failing to take protein in — you are actively pouring it out. That is why low albumin, ankle swelling and poor wound healing appear even in people eating adequate protein.
A catabolic, inflamed state. Chronic inflammation raises resting energy expenditure and drives the breakdown of muscle for fuel. This is why you lose muscle, not just fat — and why strength, grip and stair-climbing go before the number on the scale looks alarming. Muscle loss matters clinically: it worsens outcomes if you ever need surgery.
And, yes, there is a fifth: you have stopped eating properly because eating hurts. That is real, but it is a consequence of the first four, not the cause.
The Deficiencies That Follow
- Vitamin B12 — absorbed only in the terminal ileum. Ileal Crohn's or ileal resection means deficiency, and that means fatigue, brain fog, a sore tongue, and eventually tingling and numbness in the feet, which is a nerve problem you do not want to leave.
- Iron — lost through bleeding, poorly absorbed through an inflamed duodenum, and locked away in your stores by inflammation itself. Ferritin can look normal while you are functionally deficient.
- Vitamin D — needs fat to be absorbed. Fat malabsorption means low vitamin D, which in turn has consequences for bone and for immune signalling.
- Zinc and magnesium — lost in chronic diarrhoea. Zinc deficiency slows wound and tissue healing, which matters enormously if you have perianal disease.
Why Supplements Alone Are Not the Answer
Supplements are necessary. Keep taking exactly what your doctor prescribed, and keep your infusions and injections if you have them. But putting more water into a leaking bucket does not fix the leak. If the surface is inflamed and the barrier is open, more oral input is partly wasted input.
The thing that changes absorption is the state of the intestine.
What Root-Cause Correction Does
Through the LIFES protocol we treat the drivers: gut barrier and immune regulation first, with metabolic, hormonal and stress/cortisol addressed alongside.
- Phase L — Inflammatory Load Reduction (oral, 4–8 weeks). Absorption cannot normalise while systemic inflammatory signalling is high — inflammation itself blocks iron uptake and drives protein breakdown. Load comes down first, even in a gut condition.
- Phase I — Internal Correction (oral, 8–16 weeks). This is where absorption changes, because this is where the epithelial barrier, the mucus layer and the microbial environment are rebuilt. Restore the surface and the nutrition follows.
- Phase F — Functional Clearance (oral, 6–12 weeks), only after L and I are stable. Attempted first, it mobilises load faster than a depleted body can clear it and makes people worse.
- Phase S — Remission Maintenance (tapered oral, 6–12 months).
All oral. There is no procedure and no clinic visit at any stage. If your gastroenterologist has recommended exclusive enteral nutrition or intravenous iron or B12 injections, take them — those are appropriate and we work alongside them.
Honest Limits and Red Flags
If your terminal ileum has been resected, B12 by injection is likely permanent, and some bile-salt-driven fat malabsorption will remain. Extensive prior resection changes the arithmetic of what is possible. In those cases the honest goal is a lower inflammatory burden, better nutritional status and a lower medication load — not a return to your pre-diagnosis body.
Seek medical care urgently if you have: rapid unexplained weight loss, swelling of the legs or abdomen (low albumin), fainting, an inability to keep fluids down, or new numbness and tingling in the feet.
Expect Recovery Stage 1 (weeks 1–4) to show as energy and post-meal comfort. Weight, muscle and bloods move later — usually across Recovery Stages 2 and 3. Anyone promising quick weight gain is not being straight with you.
