The control of heartburn or belching can be aided by eating in moderation and avoiding oily, deep-fried or very spicy food. Reducing your caffeine intake and/or stopping smoking can also be of benefit, if relevant. Preparations such as peppermint oil may help reduce belching or colic. Sleeping with your head raised on a few pillows and long-term weight loss may also help prevent heartburn.
Dehydration – Dehydration is a common occurrence during a fast. The body continues to lose water and salts through breathing, sweat and urine; the quantity of water loss will vary depending on the weather, how much you had to drink before your fast, the degree of physical exertion and the ability of the kidneys to retain water and salts. Prevention is always better than cure. However, if you do not adequately rehydrate before a fast, your risk of dehydration is increased.
Depending on the severity of the dehydration, you may experience a general feeling of being unwell, lethargy, muscle cramps, dizziness, disorientation and even collapse or fainting.
If you are unable to stand up due to dizziness, or you are disorientated, you should urgently rehydrate with regular, moderate quantities of water, ideally with sugar and salt
If you faint due to dehydration, your legs should be raised above your head by others, and when you awake, you should urgently rehydrate as outlined above.
Headache – This is a common problem with many possible causes e.g. dehydration, hunger, inadequate rest, absence of caffeine or nicotine. Not missing the pre-dawn meal, consuming adequate quantities of fluid and if necessary taking a dose of painkillers such as paracetamol, may all go a long way towards either preventing or reducing the risk of developing a disabling headache. Headaches can also be prevented by sensible measures such as not exposing oneself to direct sunlight, wearing a hat when out, using sunglasses to reduce the effect of glare from the sun and relieving any tense muscles with a short, gentle massage.
Constipation – This is often exacerbated by dehydration and advice should be given regarding this, including dietary advice on fruit and vegetables, increasing the fibre content of food, being active etc. If the problem persists a short course of bulk laxatives may be prescribed.
Stress- Lack of food and water, changes of routine and shorter periods of sleep can all collude to increase stress levels. Hence it is important to address any potential sources of stress in order to minimise harmful effects. This can be helped by not taking on more than you can reasonably handle, not playing sports in the hot sun, controlling your anger in advance and abstaining from smoking.
Obesity- For the unwary, or those lacking in caution, food consumed during the pre-dawn and dusk meals may lead to some unintended weight gain. Obesity is an epidemic in the making, and has numerous complications in its own right.
It is ironic that you are able to become overweight or obese while you are fasting. But if you do not approach the fast with discipline and will, the opportunity to lose weight and become healthier is wasted.
