An ileus or very slowed bowel usually does best with a “bowel rest / low residue / easy to digest” style diet for a short period while motility recovers.

keep hydration up
avoid overloading the bowel
reduce hard-to-digest fibre/fat
eat small frequent amounts instead of large meals
A gentle example day could look like this:
Breakfast
White toast with a little butter or honey
Scrambled eggs
Peppermint tea or weak tea
Water/Hydralyte
Morning snack
Coconut yoghurt or plain yoghurt
Stewed/canned apple or pear
Lunch
Clear soups and broths
Plain crackers or white bread
Small amount of chicken or tofu if tolerated
Afternoon
Jelly, icy pole, or broth
Warm lemon water or peppermint tea
Dinner
White rice or mashed potato
Poached fish (like whiting)
Well-cooked pumpkin/carrot/zucchini
Fluids
Aim for regular small amounts through the day:
water
electrolyte drinks
peppermint tea
weak tea
clear soups/broths
Foods that are usually easier during recovery
White bread/toast
White rice
Plain pasta
Mashed potato
Eggs
Lean chicken/fish
Tofu
Smooth soups
Yoghurt
Stewed fruit
Crackers
Foods that often worsen bloating/slowness temporarily
Large salads
Raw vegetables
Beans/lentils/chickpeas
Wholemeal/grainy bread
Heavy creamy meals
Fried foods
Large amounts of cheese
Nuts/seeds
Large amounts of caffeine
Carbonated drinks

There actually is a growing body of research into using TENS-style electrical stimulation to improve bowel motility and chronic constipation — especially for slow-transit constipation, pelvic floor dysfunction, and neurogenic bowel disorders. I have been using my TENS machine on different parts of my body for different reasons throughout my recovery from CHS. I have found that the sacral placement has really helped with spontaneous bowel movements.

The evidence is still evolving, but it’s no longer considered “fringe.” The most studied approaches are:
Parasacral / sacral TENS
Posterior tibial nerve stimulation (PTNS/TTNS)
Abdominal interferential stimulation
Transcutaneous Neuro modulation
What researchers think is happening
The theory is that electrical stimulation may help by:
activating sacral parasympathetic pathways
improving communication between the bowel and nervous system
enhancing the gastrocolic reflex
increasing colonic contractions/transit
improving pelvic floor coordination
modulating autonomic balance (sympathetic vs parasympathetic tone)
Some papers specifically discuss stimulation triggering sacral reflexes that improve colonic motility.

Main research findings
1. Tibial nerve stimulation (ankle area)
This is one of the better-supported methods currently.
A 2024 systematic review/meta-analysis found that both:
TTNS (transcutaneous tibial nerve stimulation)
PTNS (posterior tibial nerve stimulation)
showed benefit for chronic constipation symptoms.
The tibial nerve connects into the same sacral spinal segments involved in bowel/bladder function.
Improvements reported in studies include:
more frequent bowel motions
less straining
shorter toilet time
reduced laxative use
improved quality of life
One study of 105 adults with functional constipation found significant improvement after 6 weeks of bilateral tibial stimulation, with effects persisting weeks later.

2. Sacral / parasacral TENS
This targets the lower sacral nerves directly.
Electrodes are typically placed:
over the sacrum/lower back
sometimes combined with lower abdominal electrodes
Research suggests this may help activate neural reflexes involved in:
rectal sensation
pelvic floor relaxation
colonic motility
This approach has been studied especially in:
children with chronic constipation
neurogenic bowel
slow-transit constipation
Some pediatric studies showed increased spontaneous bowel movements during treatment periods.

3. Interferential current therapy (IFT)
This uses crossing electrical currents through the abdomen/back rather than classic TENS.
This has surprisingly promising evidence for:
slow-transit constipation
treatment-resistant constipation
A randomized multicenter trial in adults found interferential therapy showed promise for improving complete spontaneous bowel movements.
Some reviews suggest IFT may currently have stronger evidence than standard TENS for constipation specifically.

4. Autonomic / vagal effects
Some newer research suggests electrical stimulation may influence:
vagal tone
enteric nervous system signaling
autonomic regulation
This is particularly interesting in people with:
chronic stress
dysautonomia
IBS
post-inflammatory gut dysfunction
nervous-system dysregulation states
But this area is still early and mechanisms are not fully proven.

Important limitations in the evidence
Researchers repeatedly note:
studies are often small
protocols vary a lot
electrode placement differs between studies
stimulation settings are inconsistent
placebo effects are substantial in neuromodulation trials
So the evidence is:
promising
biologically plausible
increasingly supported
…but not yet standardized enough for universal clinical protocols.

What people commonly use at home
The most commonly discussed home approaches are:
Sacral placement
Electrodes over:
lower sacrum
just above the gluteal cleft
sometimes lower abdomen paired with lower back
Tibial nerve placement
Electrodes:
just above the medial ankle
along the posterior tibial nerve pathway
Typical settings used in studies
These vary enormously, but often:
10–25 Hz frequencies
20–30 minute sessions
daily or several times weekly
Research protocols are not standardized enough for me to recommend exact parameters medically.

Safety considerations
TENS is usually considered relatively safe, but caution is important if someone has:
pacemakers
implanted stimulators
epilepsy
pregnancy
significant cardiac rhythm issues
unexplained abdominal pain
suspected bowel obstruction
And importantly:
TENS is generally considered an adjunct, not a replacement for:
disimpaction when needed
osmotic/stimulant regimens
hydration
bowel retraining
pelvic floor therapy
medical evaluation of chronic constipation

Overall research takeaway
The current literature suggests that neuromodulation using TENS-style stimulation may genuinely help some people with constipation and bowel dysmotility — especially:
slow-transit constipation
pelvic floor dysfunction
neurogenic bowel
chronic functional constipation resistant to standard care
The strongest emerging evidence appears to be for:
tibial nerve stimulation
interferential therapy
parasacral neuromodulation

I was SHOCKED to find out that you can use your bowels every day, yet still be chronically constipated as the colon stretches and the new stool passes over the top of the old stool you are retaining, so it just doesn’t move 😳 I would recommend anyone who has suffered from CHS to see a medical professional regarding a dis-impaction plan. Scans can be done to determine the severity of the stool burden and plans to ensure bowel movement becomes consistent can be implemented. These plans usually include a medically supervised bowel clean out phase followed by a maintenance phase using osmotic laxatives over a period of months.

Chronic constipation symptoms;
Hard, dry, difficult-to-pass stool
Straining frequently
Feeling like you haven’t fully emptied
Needing a foot stool or certain positions to go
Spending a long time on the toilet
Passing small amounts repeatedly
Alternating constipation and loose stool
“Overflow” leakage or smearing
Needing laxatives regularly
Reduced urge to poop
Feeling blocked “higher up”
Large stools that clog the toilet

Abdominal/GI symptoms
Bloating
Abdominal pressure/fullness
Excessive gas or burping
Nausea
Reduced appetite or early fullness
Reflux/heartburn worsening
Cramping
Feeling better after bowel movements
Visible abdominal distension
Feculent-smelling burps/vomiting in severe cases

Nervous system / whole-body effects people sometimes notice
These are less specific, but chronic retention and gut dysfunction can contribute to:
Fatigue
“Brain fog”
Irritability
Poor concentration
Feeling wired/tired
Sleep disruption
Feeling unwell after eating
Increased body tension or discomfort
Heart awareness or autonomic sensations around bowel activity
Reduced exercise tolerance

The gut and nervous system communicate heavily through the enteric nervous system and vagal pathways, so GI dysfunction can absolutely affect how someone feels and functions overall.

Signs suggesting long-term stool retention/impaction
Small frequent stools but never feeling “clear”
Leakage around retained stool
Diminished sensation/urge
Chronic bloating
Recurrent abdominal discomfort
Feeling stool move but not fully evacuate
Long history of symptoms from childhood
Improvement when on osmotic laxatives but relapse off them
When constipation needs prompt medical review
Seek medical assessment promptly for:
severe abdominal pain
vomiting
inability to pass gas/stool
black or bloody stool
fever
unexplained weight loss
significant abdominal swelling
dehydration
fainting
chest pain
worsening severe symptoms despite treatment

Common urinary symptoms associated with chronic constipation include:

Bladder pressure / reduced capacity
A stool-filled rectum can physically reduce bladder space.
Symptoms:
needing to pee frequently
urgency
feeling like the bladder fills very quickly
waking at night to urinate
small-volume voids
Difficulty emptying the bladder
Pelvic floor tension or rectal pressure can interfere with bladder emptying.
Symptoms:
hesitancy starting urination
weak stream
stop-start stream
feeling unable to fully empty
needing to strain to urinate
Pelvic floor dysfunction overlap
Many people with chronic constipation develop pelvic floor discoordination.
Symptoms:
constipation + urinary urgency together
needing specific positions to pee or poop
tension/spasm sensations in pelvis
pressure/heaviness
Increased risk of UTIs
Incomplete bladder emptying can increase urinary tract infection risk.
Possible signs:
burning
cloudy urine
strong odour
pelvic pain
fever (needs assessment)
Leakage/incontinence
Pressure and nerve irritation can contribute to:
stress incontinence
urgency incontinence
dribbling
post-void leakage

Severe retention can sometimes cause:
difficulty passing urine
urinary retention
overflow issues
That situation needs medical assessment promptly.
The bowel-bladder relationship is well recognised clinically — improving bowel emptying often improves urinary symptoms too, though it can take time if the pelvic floor and nervous system have been under strain for a long period.

As many of you are already aware, gut motility is slowed substantially while recovering from CHS. Foods that support gut motility generally work by one or more of these mechanisms:
increasing stool bulk and softness
stimulating the gastrocolic reflex
supporting the gut microbiome
improving hydration/electrolyte balance
providing gentle natural laxative effects
Since many of you are currently going through disimpaction/retraining, the most useful approach is usually gentle, consistent motility support rather than huge amounts of rough fibre all at once.

Best foods for gut motility
Hydrating fruits

These help soften stool and increase water content in the bowel.
Kiwifruit — one of the best studied fruits for constipation/motility
Pear
Prune
Papaya
Orange
Dragon fruit
Stewed apple

Kiwifruit is particularly interesting because it can improve motility without being as harsh as stimulant laxatives.

Soluble fibre foods
These create a soft gel-like stool that moves more comfortably through the bowel.
Oat
Chia seed
Flaxseed
Psyllium
Legume
Sweet potato
For someone with long-standing constipation, soluble fibre is often tolerated better than huge amounts of raw bran or coarse fibre.

Fermented foods (microbiome support)
These may help bowel regularity over time.
Kefir
Yogurt
Sauerkraut
Kimchi
Miso
If you already tolerate kefir/probiotics reasonably well, it is helpful. If not go slowly avoid large amounts all at once.
Healthy fats that stimulate bowel movement
Fat naturally stimulates the gastrocolic reflex.
Avocado
Olive oil
Nut
Egg
A breakfast with some fat + fluid + warmth is often excellent for morning bowel activity.

Warm fluids & motility triggers
These can help “wake up” the bowel.
Warm water
Herbal tea
Ginger tea
Coffee (if tolerated)
Warm lemon water
Soup/broth

The majority of people who have had CHS have been chronically constipated for a long time, I was shocked to learn that you can still be retaining stool even if you are using your bowels daily 😳 The colon can stretch and stool higher up in the intestinal tract is retained, to start clearing this retained stool many people do better with:
softer cooked foods
soups/stews
oats
yoghurt/kefir
fruit
adequate salt/fluid intake

It’s all about moderate fibre instead of massive fibre loading. Sometimes excessive insoluble fibre during impaction can just create more bulk behind slow-moving stool.

Foods that commonly slow motility in some people

Not “bad,” but worth watching if symptoms worsen:
large amounts of cheese
highly processed snack foods
low-fluid high-protein diets
excessive takeaway/fried foods
very low-carb diets
large amounts of red meat without fibre/fluid
chronic under-eating

A practical motility-friendly breakfast

oats
chia/flax
kefir or yoghurt
kiwi or berries
enough fluid
warm drink alongside it
That combination gives:
soluble fibre
probiotics
hydration
healthy fats
gastrocolic stimulation - Warm fluids like herbal teas upon waking, sitting on the toilet and gently pushing within 20 minutes of meals regardless of feeling the need.
