Fruit is counterproductive for protein but it's not permanent - eggs and Greek yogurt tend to be the tolerant starting point when meat and nuts aren't working.
A full obstruction at 5 weeks is the severe end of the constipation spectrum - it's a medical emergency that requires intervention rather than OTC management. Anyone experiencing that level of GI shutdown should go to urgent care rather than trying to manage it at home.
Mag07 is the next step when osmotic laxatives and fiber supplements have plateaued - the oxygen-based release mechanism is different from either and tends to produce results when the other options have not. Starting at the lower end of the dosage range and adjusting up is the right approach when switching.
magnesium is the first move for most people in this situation - the osmotic effect works well and it's easier on the system than stimulant laxatives. the high-protein low-fiber trade-off is real, you end up managing two things at once. talking to your doctor is worth it if it's been more than a few days because the options they have go further than what's over the counter
I stir a laxative powder into coffee first thing and by noon it's handled. Could also do a bigger dose to clear out fully, then bump your fiber afterward to stay ahead of it.
