Can you claim PIP for bile acid malabsorption?

What is bile acid malabsorption and why does it matter for benefits?

Bile acid malabsorption (BAM) is a condition in which bile acids are not properly absorbed in the small intestine and pass into the colon, causing symptoms that can include chronic diarrhoea, urgent bowel movements, abdominal pain, bloating, and significant fatigue. For many people, these symptoms are unpredictable and frequent enough to disrupt work, travel, and everyday tasks.

Because BAM can have a substantial impact on day-to-day life, it is a condition that the UK benefits system may take into account. According to GOV.UK, Personal Independence Payment (PIP) is designed for people aged 16 to 64 who need help with daily living or mobility because of a long-term physical or mental health condition. The key point is that PIP is not awarded on the basis of a diagnosis: it is awarded on the basis of how a condition affects you.

This distinction is important. Two people with the same BAM diagnosis may have very different experiences of the condition. One person may manage symptoms well with medication, while another may face severe, unpredictable episodes every day. The DWP assesses the second person’s experience, not the label.

Can BAM be considered a disability under UK law?

Under the Equality Act 2010, a person has a disability if they have a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities. “Long-term” means the condition has lasted, or is expected to last, at least 12 months.

For many people with BAM, the condition will meet these criteria. Chronic diarrhoea that requires frequent, urgent toilet access can affect the ability to work, travel, socialise, and perform basic household tasks. If your BAM symptoms are severe and ongoing, you may have grounds to be treated as a disabled person under the Act, which also provides protection from workplace discrimination.

Being considered disabled under the Equality Act does not automatically entitle you to PIP. The two frameworks are separate. However, establishing that your condition has a long-term, substantial impact on daily life is exactly the kind of evidence that supports a PIP claim.

How PIP is assessed: the daily living and mobility components

PIP has two components, each assessed separately.

Daily living component: This covers activities such as preparing food, eating and drinking, managing treatments, washing and bathing, managing toilet needs, dressing and undressing, communicating, reading, and engaging socially. For people with BAM, the most relevant activities are likely to be managing toilet needs (which includes urgency and incontinence), preparing food (where dietary restrictions apply), and engaging with other people (where embarrassment or fatigue caused by the condition affects social participation).

Mobility component: This covers planning and following journeys, and moving around physically. People with BAM who are anxious about being far from a toilet, or who experience such severe fatigue that walking is difficult, may score points under this component.

For each activity, you are given a score based on descriptors that describe different levels of difficulty. Citizens Advice provides a detailed breakdown of how these descriptors work. To receive the standard rate of the daily living component, you need at least eight points; for the enhanced rate, twelve. The mobility component has the same thresholds.

Eligibility rules: what you need to meet before you claim

Before making a PIP claim, you should check that you meet the basic eligibility rules, as set out on GOV.UK:

• You must be aged 16 to 64.
• Your condition must have affected your ability to carry out daily living or mobility activities for at least three months.
• You must expect those difficulties to continue for at least a further nine months.
• You must be habitually resident in England, Scotland, or Wales (separate rules apply in Northern Ireland, where PIP is administered by the Department for Communities).

BAM is typically a long-term condition, so the duration requirement is often met. The challenge for claimants is demonstrating the extent of the impact clearly and accurately on the claim form.

How to make a PIP claim for BAM: step by step

The process for claiming PIP is as follows, based on the official guidance at GOV.UK:

1. Start your claim by phone. Call the PIP new claims line on 0800 917 2222 (Monday to Friday, 8am to 6pm). You will be asked for basic personal details. A claim form called “How your disability affects you” (PIP2) will then be posted to you.

2. Complete the PIP2 form carefully. This is the most important stage. Describe your worst days, not your best. Be specific about how often symptoms occur, how long episodes last, and what you cannot do as a result. If you need to be near a toilet at all times, explain this in concrete terms.

3. Gather supporting evidence. Useful documents include letters or reports from your GP, gastroenterologist, or specialist nurse; results from a SeHCAT scan (the standard diagnostic test for BAM); a symptom diary; and any record of hospital admissions or referrals. You are not required to submit evidence, but it can significantly strengthen your claim.

4. Attend an assessment if required. The DWP may ask you to attend a face-to-face, telephone, or video assessment with a healthcare professional working on behalf of the assessment provider. You can ask for a home visit if leaving the house is difficult because of your condition.

5. Receive your decision. The DWP will write to you with the outcome. If you are awarded PIP, the letter will state which components you have been awarded and at what rate.

What to do if your claim is refused

Refusal is not the end of the process. According to Citizens Advice, you have the following options:

• Request a mandatory reconsideration. You must do this within one month of the date on your decision letter. Contact the DWP in writing and explain why you disagree with the decision, including any additional evidence you can provide.
• Appeal to a tribunal. If the mandatory reconsideration does not change the outcome, you can appeal to the Social Security and Child Support Tribunal, which is independent of the DWP. Statistics from the tribunal service show that a significant proportion of PIP appeals succeed, particularly when the claimant attends in person.

Free help with reconsiderations and appeals is available from Citizens Advice, your local welfare rights service, and charities such as Scope and Turn2us.

Where to get help and further guidance

Claiming PIP can be a demanding process, particularly when symptoms are unpredictable. The following organisations offer free, impartial support:

• Citizens Advice offers guidance on PIP eligibility, form completion, and appeals.
• Turn2us runs a benefits calculator and can help identify other entitlements.
• Scope provides a helpline for disabled people navigating the benefits system.
• Action on BAM (a UK patient group for bile acid malabsorption) may be able to provide condition-specific support and signposting, though availability of services should be confirmed directly with the organisation.
