Life is a challenge - together we are stronger

For some the challenge starts at birth as for Casper, 13 years old, with Glycogen Storage Disease type 1b. A potential life threatening disease, if a doze of cornstarch is missed his blood sugar will rapidly drop and he is at risk of having a seizure. Lifelong he needs to be meticulous and frequently take fingers pricks, day and night, to make sure his blood sugar is normal.

Others seek the ultimate challenge like Ludvig Landgren and Sarah Fager. On April 28, 2024 they will start a 250 km ultramarathon in the Namibian dessert. In 7 days they will run in temperatures likely to pass 40 degrees, be blasted by sandstorm, jumping and climbing over rocks and carrying all their food and equipment in their backpack. Even if they are prepared and ready for this race, they hope that by raising money for a good cause, will empower them even more and help them reach the finish line on May 4, 2024.

Thank you all for attending the 2024 SAGSD Conference.

Thank you all for participating SAGSD 6th GSD conference for doctors, dietitians, nurses, families and patients at Klitterhus Hotel in Ängelholm, Sweden 2024.

Its lovely to see the connecting between healthcare professionals, nationally and internationally together with patients, adults and kids. Sharing and providing information about this rare condition. Giving support and putting people in contact. A combined conference where healthcare professionals sit side-by-side with patients and families enabling interactions and learning from each other. Many interesting lectures and sessions were held from several renowned speakers. Together we improve the care for children and adults with glycogen storage disease (GSD). This has only been possible due to so many peoples interrest in attending and giving their support, both morally and economically! Thank you all!

The SAGSD president was nominated the Rare Disease Prize 2024

President Marcus Landgren was nominated by the treasurer of our association, Louise Kjærsgaard Madsen, to the Rare Prize 2024 thus due to his work for the SAGSD. This price is awarded to persons or organizations that have done something extraordinary for people living with a rare disease condition In Denmark. Marcus was nominated for his never ending work raising awareness of GSD and arranging conferences for healthcare professionals and patients in helping patients to better treatment.

On February 29, 2024, the international rare disease day, the winner was announced at an event in Copenhagen. Marcus did not win the price, but it was heartwarming to be acknowledged for his efforts for GSD over the years since the SAGSD was founded in 2011.

The event was a magnificent experience and Marcus and his family also got the opportunity to meet Her Majesty The Queen Mary of Denmark, the protector of the association for Rare Diseases in Denmark.
