Compass is still being developed and is effectively in beta. Some content and features may be incomplete, change, or not work as expected.

Content is anchored to trusted sources where available, but Compass has not yet been clinically reviewed. It provides general information rather than medical advice.

Feedback helps us identify gaps, errors, usability problems and opportunities to improve Compass over time.

How Compass is developedGive feedback

Eating and nutrition

Unintentional weight loss

Losing weight without trying to, which teams watch closely in ALS/MND.

What it means

Weight is one of the few things that can be measured easily at every visit, and a downward trend is a practical signal that intake is not keeping up. It is tracked as a trend rather than judged from a single reading.

Why you might hear it

  • It is why the scales come out at clinic.
  • It often prompts a dietitian referral.

About this explanation

These are plain explanations of words you may come across, not advice about your own situation. Where a word matters to a decision, the question pages go into it properly, and your own team is the place to take it.
