When 29-year-old Joan Amimo got a new job in Nanyuki, she had to relocate from Nairobi.

After some time in her new workplace, Amimo started experiencing extreme fatigue, memory lapses and brain fog. "I had extreme mood swings and was avoiding people since I was getting irritated quite often.

I would also struggle to wake up and go to work and would call in to report late on several occasions." Amimo had also started feeling colder than usual, and her menses suddenly started becoming heavier than usual.

At first, she dismissed the symptoms, thinking it could be due to a change of environment.
