Understanding what are the symptoms of depression can help to identify if someone is suffering from this condition, and how to get them the help they need. So let’s dive in and examine what depression is, the different types and their associated symptoms.

What is Depression?

Depression is a serious mental health disorder that affects one’s daily life. It can cause extreme feelings of sadness, hopelessness, and disinterest in activities, among other symptoms. It is more than just occasional moodiness or temporary sadness; depression can significantly impact a person's life long-term.

The American Psychiatric Association defines depression as “a period of at least two weeks during which there is either depressed mood or loss of interest or pleasure, and at least four other symptoms that reflect a change in functioning, such as problems with sleep, eating, energy, concentration, and self-image.”

Depression is a very real medical condition, and it is important to take it seriously if you think you may be affected by it. It is not something to simply “snap out of”. If you are struggling with depression, seeking out professional help should be your top priority.

Types of Depression and Their Symptoms

Depression is a serious mental disorder that can take many forms. There are several different types of depression, each of which has its own unique set of symptoms. It's important to understand the symptoms and differences between the types of depression in order to get the right diagnosis and seek the right treatment.

Major Depressive Disorder

Major Depressive Disorder (MDD) is the most common type of depression. It usually involves persistent feelings of sadness, emptiness, or hopelessness, and can have a profoundly negative impact on a person’s ability to function in everyday life. Common physical symptoms of MDD include fatigue, body aches, changes in appetite, and disrupted sleep patterns.

Persistent Depressive Disorder (Dysthymia)

Persistent Depressive Disorder (PDD), also known as dysthymia, involves a long-term, low-grade depression that persists for two years or more. People with PDD may experience difficulty concentrating, low self-esteem, and loss of interest in activities they previously enjoyed. They may also experience feelings of guilt, irritability, and fatigue.

Bipolar Disorder

Bipolar Disorder, also known as manic-depressive illness, is characterized by shifting moods and extreme highs and lows. People with Bipolar Disorder experience alternating depressive episodes that involve a loss of energy, motivation, and enthusiasm, as well as mania, which is an elevated or irritable mood accompanied by increased energy levels and activity.

Seasonal Affective Disorder (SAD)

Seasonal Affective Disorder (SAD) is a type of depression that is linked to seasonal changes, usually during the winter months. Common symptoms of SAD include decreased energy, increased sleep, oversleeping, weight gain, social withdrawal, and a lack of interest in activities.

Postpartum Depression

Postpartum Depression is a type of depression that occurs after giving birth. Common symptoms of Postpartum Depression include difficulty bonding with the baby, anxiety, feelings of worthlessness, difficulty sleeping, and fatigue. Postpartum Depression is a serious condition that requires professional treatment.

Premenstrual Dysphoric Disorder (PMDD)

Premenstrual Dysphoric Disorder (PMDD) is a severe form of Pre Menstrual Syndrome (PMS). Symptoms of PMDD include mood swings, irritability, fatigue, depression, and anxiety. These symptoms are typically experienced one week before menstruation and subside shortly after the period begins.

Psychotic Depression

Psychotic Depression is a type of depression that involves psychotic symptoms, such as hallucinations and delusions. People with Psychotic Depression experience feelings of hopelessness, despair, guilt, and suicidal thoughts. They may also have difficulty performing daily tasks and experience difficulty connecting with people.

Atypical Depression

Atypical Depression is a form of depression that differs from other types of depression in that it involves episodes of hypersomnia (excessive sleep), overeating, and sensitivity to rejection. People with Atypical Depression may also experience low energy, feelings of hopelessness, and can feel overwhelmed by minor tasks.

Depression is a serious illness that can have a profound effect on a person’s life. Knowing the different types of depression and their associated symptoms can help you to better identify when someone might be suffering from depression, and seek appropriate help.

Physical Symptoms of Depression

Depression can manifest in many forms, including physical. While the mental effects of depression may be more obvious and talked about, there are many physical symptoms associated with this illness as well.

These physical symptoms can range from mild to severe and can even be mistaken for something else, like an unrelated medical condition. That is why it is important to be aware of the physical signs of depression so that you can identify any issues early and seek help.


One of the most common physical symptoms of depression is headaches. They can range from a mild throbbing sensation to a full-blown migraine. It is believed that headaches are caused by an increased release of stress hormones.

Headaches can also make other symptoms of depression worse, like feelings of sadness, fatigue, and difficulty concentrating.

Stomach Problems

Another physical symptom of depression is stomach-related issues. This can include nausea, cramping, indigestion, vomiting, and even diarrhea. These problems may not be directly linked to depression but can be exacerbated by it, particularly if the person is feeling stressed or anxious.

Stomach problems can also be caused by medications used to treat depression, such as antidepressants.


Fatigue is one of the more common physical symptoms of depression. This can be experienced as an increase in tiredness or even feeling exhausted all of the time. This can cause someone to have difficulties getting things done or even just getting out of bed in the morning.

There are multiple causes for fatigue, including lifestyle changes, stress, and even a lack of sleep. It is important to recognize when fatigue is due to depression so that it can be addressed accordingly.

Weight Changes

Depression can also alter eating habits, which can lead to weight gain or loss. This can be a result of appetite changes due to stress or changes in lifestyle due to the person feeling too tired or unmotivated to exercise.

It is important to talk to a doctor if you experience any sudden changes in your weight, as this could be an indication of a more serious underlying issue.

Muscle Aches

Depression can also cause muscle aches or pains. This can range from a mild aching sensation to more severe pain. This occurs because of the increase in stress hormones that are released when someone is depressed.

It is important to be aware of physical symptoms of depression as they can often be an indication of a more serious underlying issue. If you are experiencing any of these physical symptoms, talk to your doctor to get a proper diagnosis.

When someone is feeling depressed, they may experience several emotional symptoms. These can range from feeling isolated and disconnected to feeling overwhelmed or helpless. They might also struggle with their self-esteem, believing that nothing they do is good enough or will make a difference. People struggling with depression can experience difficulty concentrating on tasks or making decisions, as well as apathy towards things they once enjoyed.

Depression can lead to a deep sense of sadness and hopelessness. Many people feel guilty or ashamed for not being able to overcome their feelings, as though it’s their fault for not being able to ‘snap out of it’. Low self-worth or low self-confidence can lead to feelings of worthlessness, and can prevent people from reaching out for help when they need it.

Depression can often drive a person to become more irritable than usual, or to become easily agitated. Depression can lead to feelings of anger or frustration, as well as an inability to control these emotions. These emotions can arise suddenly and without warning, leaving the person feeling confused and unsure of how to respond.

Depression can also lead to feelings of anxiousness, which can manifest in physical symptoms such as sweating, an increased heart rate or an inability to relax. People experiencing depression can feel constantly on alert or worried about the future. They can often struggle to focus or concentrate, and can be overwhelmed by their own thoughts and feelings.

In extreme cases, people who are severely depressed can become suicidal. Suicidal thoughts can cause intense fear and distress, and can be incredibly difficult to talk about. It is important to remember that these feelings are only temporary, and that there are many sources of support available. If you are feeling suicidal, please reach out to a doctor, counsellor or helpline.

Cognitive Symptoms of Depression

Depression can manifest in many different ways, and one of those is through cognitive symptoms. People with depression might experience a decrease in concentration, memory loss, and find it difficult to make decisions.

If a person with depression experiences a lack of concentration, it can be incredibly difficult to perform the tasks needed in everyday life. For instance, they may find it hard to follow conversations or have difficulty following instructions. This can also lead to difficulties at work, or in school. Memory loss can also be a symptom of depression, making it hard to recall facts, events, or names.

Making decisions can be difficult when suffering from depression. Even simple decisions such as what to eat for dinner can become overwhelming. The decision-making process can seem much more daunting than usual, leaving people stuck trying to choose.

It's important to note that these types of symptoms are not just caused by depression. Other mental health issues, such as anxiety, can also cause cognitive issues. In order to diagnose depression, a doctor must look at the whole picture and consider all possible factors.

Diagnosis of Depression

If you believe that you or someone you know is suffering from depression, it is important to reach out for help. Speaking to a healthcare professional is the best way to determine if someone is suffering from depression and what kind of treatment they may need.

A diagnosis of depression usually includes an in-depth evaluation by a qualified healthcare professional. This can include a physical and mental health assessment. The evaluation may include a discussion of symptoms, family history, current stressors, and other factors. The healthcare professional can then determine if the criteria for major depressive disorder are met.

Helpful tips for seeking help with depression include:

  • Seek Out Professional Help: Speak to your doctor or a mental healthcare provider for diagnosis and treatment options.
  • Reach Out to Supportive Friends and Family: Having a support system of trusted people can be beneficial when dealing with depression.
  • Learn About the Different Treatment Options: Become informed about the different treatments available for depression such as medications, therapy, lifestyle changes, etc.
  • Take Care of Your Physical Health: Eating healthy, exercising regularly, and getting enough rest can help improve your mental health.

Depression is a serious condition that should not be taken lightly. If you are feeling overwhelmed or hopeless, please reach out for help. A qualified healthcare professional can assess your situation and develop a treatment plan to help you manage your depression.

Treatment Options for Depression

Depression can be a debilitating condition, but fortunately there are a range of treatments available to reduce the effects of depression. Seeking treatment is important and it is best to start as soon as possible to ensure the best outcomes.

Treatments for depression are usually divided into three categories: medication, therapy or a combination of both. Each approach has its own benefits and drawbacks, so it is important to speak to a doctor or mental health professional to determine which option might be best suited to you.


Medication is a common form of treatment for depression. Common types of medication used include selective serotonin reuptake inhibitors (SSRI), monoamine oxidase inhibitors (MAOI) and tricyclic antidepressant medications. These medications work by increasing serotonin levels in the brain, which helps to improve mood. However, it can take several weeks for these medications to take effect, and they may also have side effects such as nausea, fatigue or sexual dysfunction.


Therapy is another option for treating depression. It involves regular sessions with a mental health professional who will discuss the thoughts and feelings underlying a person’s depression. This type of talk therapy can help people to understand their emotions and develop coping strategies to manage their depression.

Common types of therapy used to treat depression include cognitive behavioural therapy (CBT), interpersonal therapy (IPT) and psychodynamic therapy. These therapies can help a person to identify unhelpful thought patterns and behaviours and work towards replacing them with more positive ones.

Combination Therapy

For some people, a combination of medication and therapy might be the most effective treatment. Combining medication and therapy can help to reduce symptoms quickly, while providing long-term benefits. It is important to discuss all the options with your doctor or mental health professional before deciding on the best treatment for you.

Coping Strategies for Managing Depression

Having depression can be overwhelming and difficult to manage. It is important to find ways to cope with these feelings and build skills to help you navigate through the tough times. Here are a few coping strategies to help you manage depression.

Find Healthy Ways to Manage Your Stress

Stress can often make depressive symptoms worse, so it's important to find healthy ways to manage it. Physical activities like jogging or yoga are great ways to reduce stress. Taking breaks throughout the day to just breathe and relax can also be incredibly helpful.

Stay Connected to Loved Ones

It's easy to feel lonely and isolated when you have depression, but staying connected and interacting with people you care about can be a great source of support. Talk to loved ones about what you're going through and let them know how they can help you. You can also use technology to stay connected to those people who are far away.

Be Kind to Yourself

It's easy to slip into negative self-talk when you're feeling down, but it's important to remember to be kind to yourself. Speak to yourself in a gentle manner and practice self-compassion. Everyone makes mistakes— it's part of life. Instead of focusing on your weaknesses, try to make an effort to focus on your strengths.

Take Care of Yourself Physically

Depression can often lead to a loss of motivation and an unwillingness to take care of yourself. However, it's important to listen to your body and take care of your physical health. Eating healthy, getting plenty of sleep, and exercising can all help to improve mood and boost energy.

Seek Professional Help

If your depression is severe or hindering your daily life, it's important to seek professional help. A therapist or psychiatrist can work with you to develop a treatment plan that best fits your needs. Getting the appropriate support and treatment can help you to manage your depression more effectively.

These are just a few coping strategies that can help you to manage your depression. Remember to always take care of yourself and reach out for help when needed.
