SNP MP Amy Callaghan spent four months in hospital and underwent two life-saving surgeries after collapsing at home in June 2020, aged 28.
The East Dunbartonshire MP returned to politics as she made a virtual contribution to the House of Commons in March last year, but appeared on the green benches in person this afternoon.
She called on work and pensions secretary Therese Coffey to increase universal credit levels.
Callaghan said: â€œIn July 2020, I met my constituent Stacey, not at a constituency surgery but at the PDRU at the Queen Elizabeth University Hospital in Glasgow.
â€œWe recovered from our strokes alongside each other and I got to hear her story.
â€œToo many people like Stacey have survived catastrophic life events only to be let down by this governmentâ€™s woeful welfare system, unable to work and unable to pay for basic necessities many of us take for granted.â€
