I’ve developed terrible dry eyes. I also feel tired all the time. What could be the cause of this?
Dr Ellie Cannon replies: Dry eyes and fatigue together can be a sign that something more widespread is going on in the body.
Dry eye disease is a common condition in which the eyes do not produce enough tears, or the tears evaporate too quickly. Tears provide moisture, protection and nutrition to the surface of the eye, so a reduction causes discomfort.
In many cases, dry eyes occur as an isolated problem. Blepharitis – inflammation of the eyelids – is a frequent culprit, as are problems with the tear ducts themselves.
However, when fatigue accompanies dry eyes, it is worth investigating further. This combination can be a feature of autoimmune conditions such as lupus – which affects the joints – and Sjogren’s syndrome. These are both investigated with blood tests at the GP, which look for markers of inflammation.

Neither of these conditions are curable but the symptoms they cause can be managed with eye drops and medication. Environmental factors are also worth considering. Central heating, air conditioning and prolonged screen use all reduce blinking and dry out the eyes.
Certain medications – including antihistamines for hay fever or beta blockers – can cause dry eyes and fatigue as side effects.
I have sensitive skin and when I go into my garden I get so many insect bites. What remedies do you recommend?
Dr Ellie Cannon replies: Those with sensitive skin often develop particularly uncomfortable insect bites – but there are options.
Prevention is the most effective strategy. Wearing clothes with long sleeves and trousers, ideally with fitted cuffs, minimises exposed skin.
Keeping skin well moisturised is essential – intact skin is more resistant to bites and the infections that can follow scratching
A good insect repellent, widely available from pharmacists, should be applied before going outside. Avon Skin So Soft dry oil spray has a long history of use as an informal repellent, particularly against midges, and though it is not medically licensed for this purpose it is inexpensive and carries no known downsides.
Some people find that taking a daily vitamin B supplement helps reduce the severity of reactions, though this is not clinically proven and results vary from person to person.
For those with eczema and a tendency towards allergies, taking an antihistamine tablet on days spent in the garden can help dampen the inflammatory response before it takes hold.
