It is not uncommon for child to sweat during the night. When the sweating is severe, it is referred to a condition known as hyperhidrosis. There are numerous causes of excessive sweating amongst children during the night.

Below are some of the most common causes of hyperhidrosis in children.


Children who are severely overweight can be prone to sweating profusely at night as well as during the day. Carrying extra weight and a lack of physical activity can cause obese children to sweat heavily.

Though not all sweating is weight-related and can often be the sign of a medical condition.


If a child is feverish, the body temperature often increases, leading to excessive sweating, particularly during the night.


Tuberculosis (TB) results from the infection of bacteria which is transmitted through the air by an infected person. TB usually affects the lungs, though it can affect other organs in the body as well.

One common symptom of TB in both children and adults is excessive sweating, which is usually the result of changes in the body’s thermoregulatory system. Night sweating in TB patients is also believed to be the result of the production of cytokine by specific cells of the immune system.


Hyperhidrosis can also occur in the early stages of cancer with children. Lymphoma is a type of cancer which causes excessive sweating at night.

Emotional conditions

Anxiety, stress and other emotional conditions can lead to children sweating profusely during the night.

Oral medications for excessive sweating in children can be used as a form of treatment, including oxybutynin hydrochloride, glycopyrrolate and propantheline. However, many doctors’ advice that treatment should be more moderate until a child reaches teenage years. If the sweating is caused by an emotional condition, seeking psychological help to address the root of the condition would be advisable.

If you have any queries or concerns about hyperhidrosis and other vascular conditions in children or adults, get in touch with Daryll baker, a Consultant Vascular Surgeon.

Varicose veins, they’re unsightly and a nuisance, but they’re not life-threatening, right? Not necessarily. According to a study published recently on The JAMA Network, varicose veins could be a warning sign for potentially deadly clots known as deep vein thrombosis.

The Association of Varicose Veins With Incident Venous Thromboemolism and Peripheral Artery Disease report involved analysing the health records of more than 425,000 adults. The study concluded that varicose veins are strongly associated with deep venous thrombosis, clots which form in the deep veins of the body.

Half of the patients in the research had varicose veins and half didn’t. It found that the group of patients with varicose veins had higher incident rates for deep vein thrombosis. According to Dr. Shyueluen Chang, first author of the study:

“[Varicose veins patients] had about a five times greater risk of developing deep vein thrombosis than the other group.”

Despite the findings of the study, the researchers say that more needs to be done to understand the relationship between whether varicose veins directly result in blood clots forming, or whether the two conditions merely have a similar origin.

Varicose veins, which are typically caused by age and the weakening of the blood vessels, pregnancy and obesity, are rarely associated with serious health risks, unlike other vascular diseases, such as deep vein thrombosis (DVT), which can pose as a more serious health risk.

DVT usually occurs in a deep leg vein, which runs through the muscles of the thigh and the calf. The clot can cause swelling and pain and can lead to serious conditions such as pulmonary embolism. A pulmonary embolism refers to when a piece of the blood clot breaks off and goes into the bloodstream, blocking a blood vessel in the lungs.

If you are worried at all about varicose veins or other vascular conditions, it is wise to seek advice from a doctor or a specialist in vascular health to discuss the condition and the best form of treatment.

The vascular vein experts at the Vascular Consultancy can offer you advice about the common conditions that affect the health of the veins and what would be the best type of treatment for you.
