Have you ever thought about the reasons for bad mood, grumpiness and even anger?
If an aggressive reaction has become the norm of life, then it is worth considering what is hidden behind it.
According to Dr Helen Stokes-Lampard, from the Royal College of Physicians, such strong emotional outbursts could be caused by illness or a side effect of medication.
So here is a list of some diseases and medications that can lead to embittered states:
Overactive thyroid gland
The thyroid gland secretes hormones responsible for the level of vital energy and mood. Also, under the control of these hormones, body temperature and metabolism in the body increase. This disease is especially relevant for women. Medicines such as carbimazole, which stops excess hormone production, will help to correct the situation.
High cholesterol
Almost seven million people in the UK suffer from this. Many of them take statins (drugs that help keep cholesterol levels normal). However, every coin has two sides. The downside of these drugs is the side effects. Taking statins disrupts the balance of chemicals in the body, including serotonin. Often, uncontrollable anger is simply the effect of statins, so after stopping these drugs, a person finds calm and balanced.
Diabetes
Low blood sugar can cause sudden outbursts of anger. Low blood sugar leads to an imbalance of chemicals, including serotonin. The result is aggression, anger, confusion. Eating something sweet will improve the patient's well-being within 20 minutes. A hungry person experiences approximately the same effect. His aggressive state immediately disappears as soon as he satisfies his hunger.

Depression
This condition is characterized not only by apathy and indifference to the world around us. Irritation and anxiety are also included in this list. The last two symptoms are especially pronounced in men, because they are less prone to a feeling of hopelessness and melancholy than women. However, behavior in a depressive state can be completely different for each person. Depression can be treated with antidepressants and cognitive therapy.

Alzheimer's disease
Affects various parts of the brain, including the part responsible for human behavior. A state of nervousness and irritability may be observed in the patient several years after the onset of the disease.

Liver diseases
The most common diseases of this organ are cirrhosis and hepatitis. When the liver is damaged, toxins gradually accumulate in the blood, which affects the brain. This can lead to personality changes, sullen behavior, and angry outbursts.

Epilepsy
Epileptic seizures are caused by a sudden burst of electrical activity in the brain, which results in temporary interruptions in the normal transmission of messages between brain cells.
PMS or what is it like to be a woman?
Premenstrual syndrome is thought to be caused by an imbalance of hormones - estrogen and progesterone. This explains their irritable behavior and mood swings.
Sleeping pills
Lack of sleep can lead to serious health problems, and taking sedatives can affect mental health and only make the problem worse.
