If you have osteoporosis or low bone density, caffeine should be limited to less than 300 mg per day (approximately 2-3 cups of coffee). It is also a good idea to get extra calcium to make up for the amount that may be lost in the urine.
Complications of malaria. Malaria is a serious illness that can get worse very quickly and can be fatal if not treated promptly. It can also cause serious complications including: 1  severe anaemia â where red blood cells are unable to carry enough oxygen around the body, leading to drowsiness and weakness.
1 P. malariae, found worldwide, is the only human malaria parasite species that has a quartan cycle (three-day cycle). ( 2 The three other species have a tertian, two-day cycle.) If untreated, P. malariae causes a long-lasting, chronic infection that in some cases can last a lifetime. P. falciparum can cause severe malaria because it multiples rapidly in the blood, and can thus cause severe blood loss (anemia). 2  In addition, the infected parasites can clog small blood vessels. 3  When this occurs in the brain, cerebral malaria results, a complication that can be fatal.
