During the period of mourning, people suffer from physical problems which could also be considered as "psychosomatic".
Physical side effects of mourning can include a number fo possible ailments, ranging from headache attacks to asthma, fatigue, indigestion, constipation, impotency, skin rashes, shortness of breath, dizziness, weight loss, fainting spells, palpitation, tightness in the chest, loss of appetite, nausea, ect. More serious diseases can also be linked to bereavement, especially when the bereavement is intense.
Can anything be done about this? It is sound policy for a person who is grieving to seek frequent medical checkups; to get extra sleep, rest, and exercise; to eat well; to maintain social contacts; and to be kind to oneself. Remember: the grieving person IS more physically and emotionally fragile than usual.
