1. Insomnia or Excessive Sleep
People with depression often struggle with insomnia, waking up in the middle of the night and being unable to fall back asleep. On the contrary, some individuals may experience the opposite, feeling the constant urge to sleep and sleeping excessively. Both of these conditions are abnormal and lead to poor outcomes.
A study published in Dialogues in Clinical Neuroscience in 2008 found that nearly 75% of people with depression suffer from sleep disorders. Those with depression have difficulty falling asleep, often wake up during the night, and experience sleep disruptions. Continuous fatigue, anxiety, and stress make sleep problems worse, which in turn worsens mood.
Some may also experience nightmares or sleepwalking. Sleep disturbances are early and common signs of depression. Insomnia is not only a common issue among older adults but also affects younger people due to various reasons. Adjusting daily habits may help improve sleep for some individuals.
Sleep disorders are abnormal occurrences that can happen unexpectedly during sleep or in the transition between wakefulness and sleep. Disruptions in the sleep-wake cycle are often associated with changes in the environment. Patients may have trouble falling asleep when they want to, but may be able to sleep at other times. These disturbances don’t always cause insomnia or excessive sleep, though they often begin with complaints about these issues. Sleep-wake cycle disorders can be seen as a misalignment of wakefulness and sleep.


2. Sudden Weight Gain or Loss
You may experience an overwhelming urge to eat, leading to weight gain, or on the other hand, you may lose interest in food, resulting in weight loss. If this continues for an extended period, it’s crucial to see a doctor. Whether it’s related to depression or not, these signs are serious and should be accurately diagnosed and treated accordingly.
Chronic stress causes the body to produce more adrenaline and cortisol than normal. Cortisol leads to fat accumulation, which can contribute to obesity. Therefore, if you're feeling constantly tired, anxious, unable to sleep, or losing interest in activities you once enjoyed, it's important to consult a psychiatrist to make necessary adjustments.
Insufficient sleep increases the level of ghrelin – the hormone that signals your body it's time to eat – while decreasing leptin, the hormone responsible for making you feel full. Staying up late to binge-watch a show may cause weight gain. A study published in the journal Sleep in 2018 found that people who slept an extra hour per week burned more fat than those who slept less than an hour. Both groups consumed the same number of calories per kilogram of body weight.
If you previously had excellent memory and focus, depression may cause you to forget basic things, such as the names and phone numbers of loved ones. You may also forget work deadlines, forget to pick up your children, or struggle to make decisions. This lack of focus and memory can significantly affect both your work and personal life, leading to impulsive behaviors.


3. Reluctance to Communicate
People who avoid communication due to shyness or fear are often those with low self-esteem, feeling embarrassed when talking to strangers. Even with close ones, they struggle to find words, making their relationships increasingly distant, eventually leading to feelings of discouragement and exhaustion. These individuals don't know how to speak persuasively or entertainingly, which makes them withdraw further from conversations with others.
Individuals who dislike interacting with others tend to prefer solitude, independence, and have little desire to make new friends. While engaging with them may not present an issue, they themselves are not inclined to start conversations. This preference for solitude might have evolved into a characteristic of their personality, making them more introverted and less inclined to socialize.
Depressed individuals often limit contact with others, including family members. They avoid conversations and tend to prefer being alone. As a result, they frequently feel isolated, downhearted, and lonely. Depression doesn’t only impact the mind and emotions but can also manifest physically. Many patients report chronic joint pain or digestive issues.
People with depression often have negative thoughts, imagining and exaggerating their physical pain. No painkiller will relieve the discomfort caused by depression, as it stems from emotional distress. Only addressing the underlying depressive disorder will alleviate these symptoms. If you experience unexplained chronic pain or fatigue, it may be a sign of depression, and consulting a psychiatrist is recommended.


4. Low Self-Esteem
Feelings of being inept and useless, unable to accomplish anything meaningful. Constantly blaming oneself and overwhelmed by guilt. Feeling unworthy of both oneself and others, often retreating into isolation and avoiding interaction.
Internally, those with depression are in a constant state of self-criticism, sometimes to the point where it destroys their mood. The internal conflict, self-blame, and diminishing of one’s own worth are warning signs of severe depression. The patient often questions their own worth with thoughts such as: “I’m worthless, I should have done this, I’m not good enough…” These harmful thoughts only deepen their sadness, leading to despair.
Despair becomes a constant companion, leading the patient to believe that they are beyond help and no longer desire to seek treatment for their depression. This sense of hopelessness grows as the depression worsens. No matter what your appearance, race, religion, or background may be, always have confidence in yourself. Only you can decide what to do, what to think, and what to believe. Everyone is born, grows, and ages the same way, so there’s no reason to feel inferior to others.
If you feel the need to change in order to adapt to life, begin that change immediately. However, ensure that these changes are for your own happiness, not to impress others. Start with small actions such as helping those around you, thinking more deeply, or learning new skills and life strategies. You can improve your reading and writing skills, develop a more active lifestyle with exercise, learn time management, or change habits to continuously improve yourself.


5. Stress and Preoccupation with Death
When someone with depression experiences extreme stress and constantly questions the meaning of their life, it indicates they may be contemplating suicide. This is a clear and significant warning sign. In children, any preoccupation with how family members have passed away is a serious matter that requires attention and monitoring. These individuals often feel isolated, alone, and, above all, deeply distressed. It is important to pay close attention and attempt to offer support.
Negative thoughts, such as wanting to end one’s life or making suicide plans, are common among those suffering from depression. We may notice signs in those at risk of suicide, such as preparing for it (buying sleeping pills, ropes, gasoline, gazing vacantly from a high vantage point…), self-harming (scratching, cutting), or a history of previous suicide attempts. If these signs are present, immediate intervention and close monitoring are crucial to prevent a tragic outcome.
People with depression often create negative thoughts and amplify any pain they feel. No painkiller can relieve the emotional and psychological pain caused by depression. The anguish within the individual leads to physical sensations of pain that seem to have no physical cause. Only through proper treatment for the root cause of depression can these pain symptoms subside.
If you notice any signs of depression, do not hesitate to seek medical help or reach out to us for advice and support. Take a quick depression test to assess the severity of the condition.


6. Unusual Digestive System Symptoms
The brain and gut are strongly connected through 400-600 million nerve cells. Therefore, when a person experiences anxiety or depression, their digestive system can be affected, leading to symptoms such as abdominal pain, constipation, diarrhea, indigestion, loss of appetite, or overeating. Conversely, poor gut function can negatively impact the brain, leading to anxiety and depression.
The question of which comes first—depression or digestive disorders—remains unresolved, similar to the age-old 'Which came first, the chicken or the egg?' debate. However, research shows that these two conditions are often present together. Studies reveal that up to 50-90% of IBS (Irritable Bowel Syndrome) patients, 34% of individuals with ulcerative colitis, and 52% of those with functional dyspepsia also have at least one mental disorder, such as anxiety or depression.
Depression often causes sufferers to complain about feeling exhausted, and when combined with sleep disturbances, this fatigue worsens the anxiety. In some cases, exhaustion is expressed as stuttering, lack of activity, and slow movement.
With growing insights into the interaction between the brain and gut, scientists have now developed treatments for depression and anxiety using special probiotics (gut-friendly bacteria). You can explore more about using probiotics as a potential treatment for depression.


7. Loss of Interest in Hobbies and Sexual Activity, or Increased Irritability
People with depression often become more prone to aggression. They may experience sudden, unexplained irritability or anger, even in situations where everything seems normal to others. For example, at a family meal, while everyone is engaged in a pleasant conversation, a depressed person might feel uncomfortable, frustrated, or even upset, potentially resulting in outbursts, such as yelling or throwing utensils.
What you once enjoyed, like cooking, may lose its appeal when you're depressed. This loss of interest in activities once loved can lead to feelings of isolation and a desire to withdraw, making the depression even more intense.
Reduced interest in sexual activity is another common sign of depression. Studies show that up to 75% of those suffering from depression experience a decrease or complete loss of sexual desire, and this is considered one of the early indicators of the condition.
In the case of postpartum depression, many mothers lose interest in sex, and this can last for a period of time. Fathers should understand that this is a symptom of the illness. Sexual interest will usually return once the depression lifts. Fathers are encouraged to be patient, comforting their wives and helping them recover from postpartum depression. Gentle touches, hugs, and caressing can provide a sense of security and comfort for mothers during this time.


8. Pessimistic Attitude
Pessimism is a mental attitude where an undesirable outcome is expected from a given situation. Pessimistic individuals tend to focus on the negative aspects of life in general. While life is not always comfortable or joyful, there will be times when we feel empty, bored, or as if the world is against us. These feelings may linger, and even without any apparent reason, you may feel inexplicably sad or down. Be cautious, as this could be a sign of depression. We often assume that people around us are distancing themselves or don't care about us.
We may feel like we are all alone, as if others don't exist or can't offer any support. These pessimistic attitudes are common indicators of depression. Pessimists often seek out the worst-case scenario in every situation. Why is that? It can be understood in two ways: life can't always be perfect or fortunate, and what truly matters is your attitude toward it. If you continue living in the darkness, thinking you're unlucky, it's unlikely you'll find the motivation to rise up and improve your life.
Jealousy towards friends is another common trait of pessimists. Everywhere you look, there's suspicion and a lack of trust, as if your friends have pushed you into a life of suffering and hopelessness. However, it's important to understand that life is not something we can face alone, and not everyone is an enemy. What matters is whether or not you can recognize the good around you.


9. Constant Worry and Hopelessness
There's no apparent reason, but you constantly feel worried about the present and future. Everything seems terrible, uncertain; the future looks bleak, obscure, with no glimmer of hope. Overthinking and negative thoughts dominate your mind. Such signs are also common in depression.
Excessive worry is a mental state caused by prolonged anxiety. Those with anxiety disorders often feel irrational fear in response to all kinds of situations and are insecure about everything around them. These emotional responses are difficult to control, leaving the person trapped in an ongoing state of dread. Generalized anxiety disorder causes constant worry, even without a clear reason, affecting daily life and work. People with this condition may also experience symptoms such as insomnia, restlessness, stomach discomfort, anxiety, and fatigue.
Sleep problems are common: unable to sleep soundly, feeling unrested even after waking, and struggling to calm down. Irrational fear takes over: rapid heart rate, frequent panic attacks, shortness of breath, trembling hands, nausea, and sometimes a sense of losing control or feeling like you're going crazy. Some sufferers also have a fear of crowds or being alone, avoiding public places.
Emotional signs include excessive worry and fear over things that aren't really threatening, a constant fear of death, irritability, difficulty concentrating, restlessness, and an overwhelming sense of impending doom. Physical symptoms include rapid heartbeat, sweating, stomach cramps, dizziness, frequent urination, shallow breathing, trembling, muscle spasms, headaches, fatigue, and persistent insomnia.


10. Feeling Constantly Fatigued, Lacking Interest
You feel in a constant state of fatigue, with no energy or strength left. There's no interest in anything, even in things that once brought you joy. The sense of pleasure is gone, and life feels uninteresting. You lack motivation and don’t want to do anything. Days feel long and endlessly draining.
Fatigue can stem from underlying health issues, but it’s also often connected to the small, everyday stresses. While stress is a natural part of life, chronic stress contributes to physical and emotional discomfort. Overwhelming stress weakens the body, leading to headaches, muscle tension, and anxiety.
Energy drinks, loaded with sugar and caffeine, are often used by those who need to stay alert. However, they can lead to even more fatigue later on. Refined carbs in junk food, sweets, and sugary drinks spike glucose levels in the blood, providing a quick burst of energy, but this leads to inevitable crashes, leaving you more tired afterwards.
Adults need at least 7 hours of sleep each night. Regularly getting inadequate sleep increases the risk of diabetes, high blood pressure, heart disease, stroke, depression, weakened immunity, increased pain, and reduced function. According to the National Sleep Foundation, poor sleep is when it takes longer than 30 minutes to fall asleep, you wake up more than once during the night, or if you stay awake for over 20 minutes after waking up in the middle of the night.
