IBD and Exams: How to Improve Focus and Energy

Exams can be demanding at the best of times. When a young person is also managing IBD, it often becomes more complex.

You may notice:

• energy that feels inconsistent or easily depleted

• brain fog or slower thinking

• difficulty concentrating for sustained periods

• needing more breaks than their peers

This isn’t about effort.

With IBD, there are additional factors at play:

• ongoing inflammation

• increased nutrient demands

• the impact of medication

• disrupted appetite, especially in the morning

• changes in digestion and absorption

On top of this, stress around exams can further affect both energy levels and symptoms.

The aim is not to push harder, but to support the body so focus and energy become more stable and reliable.

What often gets in the way

In practice, a few patterns commonly show up:

• skipping breakfast because appetite is low or nausea is present

• relying on quick, easy foods that are low in protein

• long gaps between eating, especially during school days

• avoiding foods due to symptoms, leading to a more limited intake

• low fluid intake, particularly when busy or fatigued

These are all understandable, but they can make it harder to maintain steady energy and concentration.

How to improve focus and energy (simple, practical steps)

⚡️ Start with a realistic breakfast (not a perfect one)

Many teens with IBD don’t feel like eating first thing.

Sometimes this can be due to:

• nausea

• low appetite

• early morning symptoms.

Forcing a large breakfast is rarely helpful. Instead, aim for something small, gentle and protein-containing. Options that tend to work well:

• a smoothie with protein powder, milk or milk alternative, nut butter and berries

• Greek yoghurt with nut butter or seeds

• an omelette, scrambled/poached egg on toast

• even a few sips of a protein smoothie to start

The goal is simply to give the brain some fuel early on, even if it’s small.

⚡️ Change food combinations to reduce energy crashes

When appetite is low or food choices are limited, it’s common to rely on:

• toast

• cereal

• snack foods

These can give a quick lift in energy, but often lead to a drop in focus later.

Rather than removing foods, focus on pairing them:

• toast → add eggs, nut butter, hummus or avocado

• cereal → add Greek yogurt, or protein enriched plant milk/soya yogurt, mixed seeds and berries

• fruit → add Greek yoghurt or a handful of nuts, or generous drizzle of nut butter

• snacks → include some protein or healthy fat (e.g. avocado, olive oil, olives, seeds, nuts)

This is often more realistic and better tolerated.

⚡️ Build meals that sustain energy (within tolerance)

IBD often means working within what feels manageable. Where possible, aim for meals that include:

• protein (chicken, fish, eggs, tofu, yoghurt)

• fats (olive oil, nuts/nut butter, seeds/seed butter)

• carbohydrates (rice, potatoes, or oats)

This combination supports more stable energy, better concentration, and fewer dips through the day.

Keep meals simple, familiar and easy to digest, especially during exams.

⚡️ Include nutrients to support concentration

The brain relies on specific fats to function well. Omega-3 fats support:

• concentration and mental clarity

• memory and learning

• mood stability

They may also help regulate inflammatory pathways, which is relevant in IBD.

Aim for oily fish around 2 times per week, such as wild salmon, mackerel, or sardines.

If this isn’t realistic a quality omega-3 supplement can be used as a backup.

Another great addition is choline, playing an important role in brain signalling and concentration. Eggs are one of the best sources, so if your young person likes them, they can be a really useful addition - at breakfast or as a snack.

⚡️ Support key nutrients that are often under strain

With IBD, nutrient demands can be higher, and absorption may be reduced.

Key nutrients involved in energy and focus include iron, B vitamins, and magnesium.

If a young person is experiencing:

• fatigue

• low stamina

• difficulty concentrating

it may be worth reviewing their food nutrient intake or recent blood test results. Further nutritional evaluation testing may also help where appropriate.

⚡️ Keep energy steady with regular intake

Long gaps without eating can:

• increase stress hormone output

• lead to energy dips

• make concentration harder

This can be more pronounced in IBD.

Even small, regular meals or snacks can help maintain more stable energy.

This is particularly helpful on school days where routine can otherwise lead to long gaps.

⚡️ Don’t overlook hydration

Low fluid intake is a common contributor to:

• fatigue

• headaches

• reduced concentration

This can be more relevant in IBD, particularly if stools are loose or more frequent.

Simple steps:

• encourage regular drinking through the day

• keep fluids easily accessible during revision

• consider electrolytes if energy dips are noticeable

If your young person has a stoma or a J-pouch, fluid and electrolyte needs can be quite different. In these cases, higher sodium intake is often needed, and standard electrolyte drinks may not always be the best fit. Tailoring this more specifically can make a noticeable difference to energy and hydration.

What parents often notice when this improves

When these foundations are in place, it’s common to see:

• more stable and predictable energy

• improved ability to concentrate

• fewer energy crashes during the day

• better engagement with revision

These changes are often gradual, but meaningful.

A simple starting point

If this feels like a lot, start with:

• a small, protein-containing breakfast

• pairing carbohydrates with protein or fat

• regular hydration, starting in the morning and maintaining through the day

These alone can start to make a noticeable difference to IBD and exams.
