Dear Dr Robertson,

I have been spending a lot of time on business in one of the eastern Caribbean islands for about two years now. I have noticed over the last 12 months that my immune system is taking a beating which has manifested itself in upper respiratory challenges (colds, sinus conditions, etcetera).

Recently, I was diagnosed with an ear infection as a result of sinus drain. I went to the doctor and was given antibiotics which cleared up the situation. However, within 10 days, the condition was back. I have since done some research which indicates that the use of antibiotics for such a condition is not the best treatment as the condition tends to recur. I need your guidance to rid myself of the problem but more importantly, to improve my immune system to prevent these upper respiratory conditions.

Dear Reader,

Constant travelling and island hopping will affect the upper respiratory health manifesting as allergies, watery eyes and ferocious sneezing. This is usually caused by certain sprays used in-flight before boarding your plane. There is also exposure to allergens on board or exposure to outdoor pollen that is invisible to the eyes. Another factor could be food allergies which could follow within minutes or hours after eating. You could narrow down your 'food suspects' from the following list of foods — concentrated sugars, chocolate, eggs, citrus fruits, corn, coffee, beef, pork, and dairy products. Remember that bacteria thrive on sugar.

Burning garbage

Sinusitis is due to constant inhalation of 'refuse burning' (garbage) and exposure to cigarette smoke or other irritants. Dehydration from colds and fever adds to the problem, and this is why excess fluids must be taken so that the mucus runs freely, and not thicken.

What you should do

1. Drink large amounts of water.

2. Use sterile water generally in a sterile spray bottle and squirt in the nostrils to soothe the nasal tissues. A pharmacist can prepare this for you.

3. When you have an attack of sinusitis try a hot pack over the sinuses with a combination of drops of eucalyptus oil and menthol or Olbas oil. You can also use an inhalation steamer with the oils as directed.

4. Try to keep a record of the foods that you eat and which you may be allergic to, and avoid them.

5. If you do feel uncomfortable as if you cannot breathe use the sterile water spray to release 'clogginess'.

Supplements to take

1. Vitamin C - 1000mg daily with bioflavonoids.

2. Vitamin A. 25,000 iu daily.

3. Omega 3,6,9, soft gels 1000mg; take two daily.

4. Garlic soft gels, 500mg daily (take when there is an infection).

5. Acidophilus capsules; at least 50mg before a meal daily.

Remove acidic juices from the diet and have instead juices and drinks that are alkaline such. as coconut water and plain, purified water. Also, have more warm broths. After a meal, have papaya or 'enzyme chewable'.

One-week detox

Use coconut water as your water and no sugary sweeteners. Drink one tablespoon of aloe vera juice first thing in the morning blended with a small amount of fruit juice to conceal the bitterness for seven days or more.
