The reality TV star was briefly hospitalised after she felt unwell during a plan journey from Paris to Los Angeles earlier this month. Her boyfriend has advised her to relax and take rest.
"Kardashian is not feeling well from the last few weeks. West has asked her to slow down. Even her mom has been warning her to slow down. She has been working hard and not taking rest at all," femalefirst.co.uk quoted a source as saying.
"Kardashian now realises she can't do it all the way she used to. She has to think about the baby's needs. It's definitely an adjustment," the source added.
Doctors have advised her to reduce the work load and do proper exercise.
"Kim's not respecting her pregnancy. She has been running around working out seven days a week. She's working with two different trainers to control her weight, including Tracy Anderson and a pregnancy trainer," the source said.
